description

The 'ACT16952 are 16-bit registered transceivers that contain twosets of D-type flip-flops for temporary storage of data flowing ineither direction. They can be used as two 8-bit transceivers or one16-bit transceiver. Data on the A or B bus is stored in registers onthe low-to-high transition of the clock (CLKAB or CLKBA) input,provided that the clock-enable ( or ) input is low.Taking the output-enable ( or) input lowaccesses the data on either port. To avoid false clocking of theflip-flops, (or ) should not be switched from lowto high while CLKAB (or CLKBA) is low.

The 74ACT16952 is packaged in TI's shrink small-outline package,which provides twice the I/O pin count and functionality of standardsmall-outline packages in the same printed-circuit-board area.

The 54ACT16952 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. The74ACT16952 is characterized for operation from -40°C to85°C.
