description

This 16-bit registered transceiver is designed for 2.7-V to 3.6-V V_CC operation.

The SN74ALVC16952 contains two sets of D-type flip-flops for temporary storage of data flowing in either direction. It can be used as two 8-bit transceivers or one 16-bit transceiver. 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 ( or ) input is low. Taking the output-enable ( or ) input low accesses the data on either port.

The SN74ALVC16952 is available in TI's shrink small-outline (DL) and thin shrink small-outline (DGG) packages, which provide twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.

The SN74ALVC16952 is characterized for operation from -40°C to 85°C.
