8-Line To 1-Line Data Selectors/Multiplexers

These data selectors/multiplexers contain inverters and drivers that supply full data selection to the four output gates. A separate strobe (G)\ input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs. The ’HC158 devices’ outputs provide inverted data. These data... Read More

These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs. The ’HC163 devices are 4-bit binary counters. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when instructed by the count-enable (ENP, ENT) inputs and...

The ’HC164 and ’HCT164 are 8-bit, serial-in, parallel-out, shift registers with asynchronous reset. Data is shifted on the positive edge of Clock (CLK). A LOW on the RESET (CLR) pin resets the shift register and all outputs go to the LOW state regardless of the input conditions. Two Serial Data... Read More

The SNx4HC165 devices are 8-bit parallel-load shift registers that, when clocked, shift the data toward a serial (QH) output. Parallel-in access to each stage is provided by eight individual direct data (A–H) inputs that are enabled by a low level at the shift/load (SH/LD) input. The SNx4HC165 devices also feature...

High Speed CMOS Logic Quad D-Type Flip-Flops with 3-State Outputs

The SNx4HC174 contains six positive-edge-triggered D-type flip-flops with shared clock (CLK) and clear (CLR)inputs. The SNx4HC174 contains six positive-edge-triggered D-type flip-flops with shared clock (CLK) and clear (CLR)inputs.

These positive-edge-triggered D-type flip-flops have a direct clear (CLR) input. The ’HC175 devices feature complementary outputs from each flip-flop. These positive-edge-triggered D-type flip-flops have a direct clear (CLR) input. The ’HC175 devices feature complementary outputs from each flip-flop.

The ’HC191 devices are 4-bit synchronous, reversible, up/down binary counters. Synchronous counting operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple-clock)... Read More

The ’HC192, ’HC193 and ’HCT193 are asynchronously presettable BCD Decade and Binary Up/Down synchronous counters, respectively. Presetting the counter to the number on the preset data inputs (P0-P3) is accomplished by a LOW asynchronous parallel load input (PL)\. The counter is incremented on the low-to-high transition of the Clock-Up input... Read More

The device is useful in a wide variety of shifting, counting and storage applications. It performs serial, parallel, serial to parallel, or parallel to serial data transfers at very high speeds. The two modes of operation, shift right (Q0-Q1) and parallel load, are controlled by the state of the Parallel... Read More

This device contains two independent 4-input NAND gates. Each gate performs the Boolean function Y =A ● B ● C ● Din positive logic. This device contains two independent 4-input NAND gates. Each gate performs the Boolean function Y =A ● B ● C ● Din positive logic.

The ’HC221 and CD74HCT221 are dual monostable multivibrators with reset. An external resistor (RX) and an external capacitor (CX) control the timing and the accuracy for the circuit. Adjustment of RXand CXprovides a wide range of output pulse widths from the Q and Q\ terminals. Pulse triggering on the B... Read More
