74LVT2952 3.3 V Octal registered transceiver; 3-State Rev. 4 — 11 September 2013 Product data sheet 1. General description The 74LVT2952 is a high-performance BiCMOS product designed for VCC operation at 3.3 V. This device combines low static and dynamic power dissipation with high speed and high output drive. The 74LVT2952 device is an 8-bit registered transceiver. Two 8-bit back-to-back registers store data flowing in both directions between two bidirectional buses. Data applied to the inputs is entered and stored on the rising edge of the clock (CPxx) if the clock enable (CExx) is LOW. The data is then present at the 3-state output buffers, but is only accessible when the output enable (OExx)) is LOW. Data flow from An inputs to Bn outputs is the same as for Bn inputs to An outputs.
