Texas Instruments SN74LV367ANSR

Overview

SN74LV367ANSR from Texas Instruments is a hex noninverting buffer/line driver with 3-state outputs, designed for bus-oriented applications including memory address driving, clock distribution, and I/O expansion. 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 and 3-state outputs for LED matrix and 7-segment display control.

For engineers reviewing the SN74LV367ANSR datasheet, SN74LV367ANSR pinout, SN74LV367ANSR application, or SN74LV367ANSR equivalent, key selection criteria include its dual-output-enable architecture (1OE/2OE), 16-pin SOP (NS) package, 3.3 V/5 V logic compatibility, ±8 mA output drive at 3 V, and Ioff partial power-down protection - all critical for industrial bus interface and display driver designs.

Technical Context

The SN74LV367ANSR implements dual 4-line + 2-line buffer organization with active-low 3-state controls (1OE and 2OE), enabling independent enablement of two functional groups. Each buffer passes noninverted A-inputs to Y-outputs when OE is low; outputs enter high-impedance state when OE is high.

It integrates balanced CMOS push-pull outputs with symmetrical sourcing/sinking capability (±8 mA at 3 V), Ioff protection that disables outputs at 0 V VCC, and input clamp diodes for ESD robustness. Its design targets low-noise, low-ringing bus interfacing - confirmed by typical VOLP < 0.8 V and VOHV > 2.3 V at 3.3 V.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating voltage for SN74LV367ANSR?

The SN74LV367ANSR supports a recommended operating VCC range of 2 V to 5.5 V. Absolute maximum supply voltage is 7 V, but sustained operation above 5.5 V risks permanent damage. At 5 V, it achieves its fastest propagation delay (≤7 ns), making it suitable for both 3.3 V and legacy 5 V system integration without level shifters.

Does SN74LV367ANSR support 5 V tolerant inputs?

Yes, SN74LV367ANSR inputs are 5 V tolerant - they accept VI up to 5.5 V regardless of VCC level. This enables direct interfacing with 5 V logic families (e.g., TTL, older microcontrollers) while operating from a 3.3 V supply, simplifying mixed-voltage system design without external translators.

How does the dual output-enable architecture of SN74LV367ANSR benefit system design?

SN74LV367ANSR features two independent active-low output enables (1OE and 2OE), controlling separate groups of outputs (Group 1: pins 3,5,7,9; Group 2: pins 11,13). This allows time-multiplexed bus sharing, selective peripheral activation, and reduced contention - critical for LED matrix row/column sequencing and memory address decoding in resource-constrained systems.

What thermal considerations apply to SN74LV367ANSR in continuous operation?

SN74LV367ANSR in NS package has a junction-to-ambient thermal resistance (RθJA) of 64 °C/W. At maximum 16 mA output current per pin and 5.5 V supply, power dissipation remains low (<20 µA ICC quiescent), but PCB layout must include adequate copper pour and thermal vias under the package to maintain junction temperature within –40°C to +125°C limits under worst-case ambient conditions.

Is SN74LV367ANSR suitable for hot-swap applications?

Yes, SN74LV367ANSR includes Ioff circuitry that disables all outputs when VCC = 0 V, limiting off-state leakage to ≤5 µA. This prevents back-driving powered circuitry during insertion/removal - a key requirement for hot-swap backplanes and modular industrial I/O systems where SN74LV367ANSR serves as a robust interface buffer.
