概述
Description
SN74ALVCF162835GR is a high-speed, 16-bit buffer/driver (bus transceiver) from TI’s ALVC family. It provides bidirectional data buffering between two 8-bit buses (often labeled A and B) with tri-state outputs. A DIR control selects the data flow direction, and OE signals tri-state the respective outputs, allowing the device to connect or isolate buses as needed. It’s designed for low-voltage operation (typical 1.65–3.6 V), offering fast performance with low power for interfacing microprocessors, memory, and other digital peripherals. The GR suffix indicates RoHS-compliant (Pb-free) packaging. Applications include bus interfacing, level shifting between domains, and buffering to protect and isolate digital paths.

Pinout
- Pin count: 20 pins (SOIC/TSSOP/SSOP-20, etc.).
- Function: SN74ALVCF162835GR is a dual 8-bit, non-inverting buffer/driver with 3-state outputs. It provides two 8-bit buffer banks (total 16 data lines) with independent output-enable controls (one per bank) to tri-state each bank. Used to buffer a 16-bit bus on a low-voltage CMOS family.
