ActiveOCTAL BUS TRANSCEIVERS AND REGISTERS WITH 3-STATE OUTPUTS
Description
General part information
74ABT2952 Series
The 'ABT2952A transceivers consist of two 8-bit back-to-back registers that store data flowing in both directions between two bidirectional buses. Data on the A or B bus is stored in the registers on the low-to-high transition of the clock (CLKAB or CLKBA) input provided that the clock-enable (CLKENAB\ or CLKENBA\) input is low. Taking the output-enable (OEAB\ or OEBA\) input low accesses the data on either port.
To ensure the high-impedance state during power up or power down, OE\ should be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT2952A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT2952A is characterized for operation from -40°C to 85°C.
