概述

Description

The 74LCX541FT is an octal buffer/line driver with 3-state outputs from the 74LCX CMOS family. It buffers an 8-bit data bus (A0–A7) to eight outputs (Y0–Y7) and uses two independent, active‑low enables (OE1 and OE2) to tri-state each 4‑bit half. It is non-inverting, used to widen a data bus, isolate loads, or level-shift between devices in low-voltage systems.
Key points:
- 8-bit buffer with two 4-bit sections, each with its own active-low OE
- Non-inverting, tri-state outputs
- Low-voltage CMOS device (typical operation in the 2.0–3.6 V range; check datasheet for exact Vcc)
- Package: 20-pin (common SOIC/related), FT suffix indicates packaging/lead-free/tape-and-reel variants
Typical usage:
- Tie OE1 and OE2 low to enable outputs; raise them to tri-state.
- Use as a data buffer or bus-expansion between ICs or microcontrollers within a compatible voltage level.

Features

Here are the key features of the 74LCX541FT (octal buffer/line driver with 3-state outputs):
- 8-bit, noninverting buffer/driver with three-state outputs
- Vcc range: 2.0 V to 3.6 V (LCX family) for compatibility with 3.3 V logic
- D0–D7 inputs; Q0–Q7 outputs
- Output Enable (G or OE) to place all outputs in high-impedance state
- Ioff specification for partial-power-down (no back-powering when Vcc is 0)
- CMOS low-power operation with reduced static/dynamic power
- TTL/CMOS-compatible input thresholds and good noise margins
- ESD protection (typical robust protection for handling static)
- Suitable for bus driving and interfacing multiple devices
- Packaging options (FT variant refers to available package type, e.g., small-outline packages)
Note: Exact OE polarity and package details depend on the specific datasheet variant.

Package

20-pin TSSOP (Thin Shrink Small Outline) package.

Pinout

- Pin count: 20 pins (DIP-20/SOIC-20)
- Function: Octal buffer/line driver with 3-state outputs. It provides eight data inputs (A1–A8) and eight buffered outputs (Y1–Y8) with an enable control (G) that tri-states the outputs when active.

Manufacturer

Manufacturer: Nexperia. Nexperia is a Dutch semiconductor company (formerly part of Philips/NXP) that designs and manufactures discrete components, logic ICs, MOSFETs, and protection devices for global markets (automotive, industrial, and consumer).

Application

74LCX541FT is an 8-bit D-type transparent latch with 3-state outputs. Applications:
- Bus buffering/interfacing in microprocessor/microcontroller systems
- Latching multiplexed address/data lines (address latch)
- 8-bit data storage/register between CPU and peripherals
- Buffer/driver for memory and I/O buses
- Bus isolation and level-shifting in high-speed logic networks
