SN74ALVCH16952DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16952DGGR is a 16-bit registered transceiver with 3-state outputs from the Texas Instruments Widebus family. It operates on a single VCC supply ranging from 1.65 V to 3.6 V and utilizes an EPIC submicron CMOS process. The device integrates two sets of D-type flip-flops for temporary data storage, allowing it to function as either one 16-bit or two 8-bit transceivers. Data transfers occur on the low-to-high clock transition when enabled. It features active bus-hold circuitry to maintain valid logic levels on unused inputs without external resistors.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle floating data inputs?

Active bus-hold circuitry is provided on the data inputs to hold unused or floating inputs at a valid logic level, removing the requirement for external pullup or pulldown resistors.

What triggers the data storage in the registers?

Data on the A or B bus is stored in the registers on the low-to-high transition of the respective clock (CLKAB or CLKBA) input, provided the clock-enable input is low.
