SN74LVC2952APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2952APWR is an octal bus transceiver and register with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation on all ports. The device consists of two 8-bit back-to-back registers that store data flowing in both directions between two bidirectional buses. Data is stored on the low-to-high transition of the clock input when the clock-enable input is low. Taking the output-enable input low accesses the data on either port.
