概述

Description

PI49FCT3807QEX is a device in the PI49FCT family (from Pericom/Renesas) that provides an 8-bit buffer interface with tri-state outputs. It buffers and protects data/address lines and helps isolate buses between logic devices or voltage domains. Typical features include eight buffered I/O lines, a global output enable, low-leakage tri-state, and operation from standard supply rails (commonly 3.3V or 5V). The QEX suffix indicates RoHS-compliant packaging. Common applications are processor/microcontroller bus buffering, memory interfaces, and backplane interconnects. For exact electrical characteristics, timing, pinout, and packaging, consult the official PI49FCT3807QEX datasheet on Renesas/Pericom’s site or distributor portals. If you share the datasheet or link, I can extract a precise, up-to-date summary.

Features

Here are the typical features of PI49FCT3807QEX (bus transceiver family). For exact specs, refer to the datasheet.
- 8-bit bidirectional buffer/transceiver with tri-state outputs
- A and B data ports with DIR control to select A→B or B→A
- Output Enable (OE) to place outputs in high-impedance state
- CMOS/FCT technology for low power
- Wide operating voltage typical: 2.3V–3.6V (check datasheet for exact ranges)
- TTL/CMOS-compatible input thresholds
- ESD protection on I/O pins
- RoHS-compliant in a compact QEX package (as specified)
- Applications: bus interfacing, backplane/bus isolation, microprocessor/peripheral data paths
Note: exact voltage ranges, drive strength, propagation delay, and package details should be confirmed from the official datasheet.

Package

QFN-20 package with exposed pad (QEX).

Pinout

Pin count: 20 pins.
Function: PI49FCT3807QEX is an 8-bit bidirectional bus transceiver (octal data buffer) with tri-state outputs. It provides two 8-bit ports (A and B), with a direction control input (DIR) and an output-enable control (OE) to buffer data between buses, suitable for crossing voltage/domains or isolating buses.

Application

Application areas:
- 8-bit bidirectional bus transceiver with 3-state outputs
- Buffering/isolating data and address buses
- Level shifting between voltage domains
- Interfaces between microprocessors, memory, and peripherals
- Backplane or inter-board data paths and clock-domain crossing buffers
