Texas Instruments SN74LV367APWT

Overview

SN74LV367APWT from Texas Instruments is a hex noninverting buffer/line driver with 3-state outputs, designed for bus-oriented applications including memory address driving and clock distribution. It operates from 2 V to 5.5 V, delivers ≤7 ns propagation delay at 5 V, supports mixed-mode voltage translation, and features balanced CMOS push-pull outputs with ±35 mA drive capability - used in LED matrix and 7-segment display control.

For engineers reviewing the SN74LV367APWT datasheet, SN74LV367APWT pinout, SN74LV367APWT application, or SN74LV367APWT equivalent, key selection considerations include its dual 4-line + 2-line buffer architecture, active-low 3-state enable inputs (1OE, 2OE), 16-pin TSSOP package, Ioff partial power-down support, and 5-V-tolerant inputs enabling level-shifting from higher-voltage logic domains.

Technical Context

The SN74LV367APWT implements two independent 3-state buffer groups: one with four channels (1A1–1A4 → 1Y1–1Y4) and another with two channels (2A1–2A2 → 2Y1–2Y2), each controlled by dedicated active-low output enables (1OE, 2OE). Its logic diagram confirms noninverting functionality and high-impedance state activation on OE high.

It integrates balanced CMOS push-pull outputs capable of sourcing/sinking up to ±35 mA per channel, with dynamic noise characteristics specified at VOLP < 0.8 V and VOHV > 2.3 V (VCC = 3.3 V, TA = 25°C). The device includes Ioff protection, allowing safe operation during partial power-down when VCC = 0 V.

FAQ

What is the recommended power supply decoupling for SN74LV367APWT?

A 0.1 µF ceramic capacitor must be placed within 2 mm of Pin 16 (VCC) and Pin 8 (GND) to suppress high-frequency switching noise. For systems with multiple SN74LV367APWT devices or heavy load transients, add a 1.0 µF bulk capacitor nearby. This ensures stable 3-state transitions and minimizes ground bounce observed in LED matrix applications.

Does SN74LV367APWT support 5 V logic inputs when powered from 3.3 V?

Yes, SN74LV367APWT accepts input voltages up to 5.5 V regardless of VCC setting - enabling direct connection of 5 V microcontroller outputs to its A-inputs while operating from a 3.3 V supply. This down-translation capability eliminates external level shifters in mixed-voltage systems using SN74LV367APWT.

How should unused inputs be handled on SN74LV367APWT?

All unused inputs on SN74LV367APWT must be tied to either VCC or GND to prevent floating states that cause excessive current draw or erratic output behavior. Inputs tied to VCC default to logic high; those tied to GND default to logic low. Do not leave any input unconnected - this is critical for reliable operation in industrial environments.

What is the maximum output current per channel for SN74LV367APWT?

SN74LV367APWT supports ±35 mA continuous DC output current per Y-output (Pin 3, 5, 7, 9, 11, or 13) under recommended operating conditions. This allows direct driving of LEDs, small relays, or terminated transmission lines. Exceeding this limit risks thermal damage; always verify total package power dissipation using RθJA = 131.2 °C/W for the PW package.

Is SN74LV367APWT pin-compatible with older SN74LS367A devices?

No, SN74LV367APWT is not pin-compatible with SN74LS367A. While both are hex buffers with 3-state outputs, SN74LV367APWT uses a 16-pin TSSOP (PW) package with different pin assignments - notably dual OE inputs (Pins 1 and 15) and split buffer grouping - whereas SN74LS367A uses a 16-pin SOIC with single OE and different functional partitioning. PCB redesign is required for substitution.
