Description

The 'ABT16470 are 16-bit registered transceivers that contain two sets of D-type flip-flops for temporary storage of data flowing in either direction. The 'ABT16470 can be used as two 8-bit transceivers or one 16-bit transceiver. Separate clock (CLKAB or CLKBA) and output-enable (OEAB\ or OEBA\) inputs are provided for each register to permit independent control in either direction of data flow. To avoid false clocking of the flip-flops, clock enable (CLKEN\) should not be switched from high to low while CLK is high. 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 SN54ABT16470 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT16470 is characterized for operation from -40°C to 85°C.
