Texas Instruments SN74LV367APWRG4

Overview

SN74LV367APWRG4 from Texas Instruments is a hex noninverting buffer/line driver with 3-state outputs, designed for 2 V to 5.5 V operation. It features dual output-enable controls (1OE, 2OE), 7 ns max propagation delay at 5 V, ±35 mA output drive, and mixed-mode voltage interface capability - used in LED matrix and 7-segment display control systems.

For engineers reviewing the SN74LV367APWRG4 datasheet, SN74LV367APWRG4 pinout, SN74LV367APWRG4 application, or SN74LV367APWRG4 equivalent, key selection criteria include 3-state timing behavior, VCC-tolerant inputs, ground-bounce/undershoot performance, and TSSOP-16 package compatibility with high-density PCB layouts.

Technical Context

The SN74LV367APWRG4 implements two independent 3-state buffer groups: one 4-line (1A1–1Y4) and one 2-line (2A1–2Y2), each controlled by active-low OE pins. Its balanced CMOS push-pull outputs support bidirectional current sourcing/sinking up to ±35 mA per channel while maintaining low dynamic noise (VOLP < 0.8 V, VOHV > 2.3 V at 3.3 V).

It supports partial power-down (Ioff) with ≤5 µA off-state leakage and includes input clamp diodes for ESD robustness (±2000 V HBM). The device operates across –40°C to +85°C and enables mixed-voltage interfacing - e.g., 5-V inputs driving 3.3-V buses - without level shifters.

FAQ

What is the maximum output current rating for SN74LV367APWRG4?

The SN74LV367APWRG4 supports ±35 mA continuous output current per Y terminal under recommended operating conditions. This rating applies across the full VCC range (2–5.5 V) and enables direct LED driving or termination of moderate-capacitance buses without external amplification. Exceeding this limit risks thermal damage or parametric shift.

Does SN74LV367APWRG4 support 5-V input signals when powered at 3.3 V?

Yes, SN74LV367APWRG4 accepts input voltages up to 5.5 V regardless of VCC setting - including when VCC = 3.3 V. This 5-V-tolerant input capability allows seamless interfacing between 5-V microcontrollers and 3.3-V peripherals without level-shifting circuitry, simplifying design and reducing BOM count.

How does the Ioff feature function in SN74LV367APWRG4?

The Ioff feature in SN74LV367APWRG4 disables all outputs and limits leakage to ≤5 µA when VCC = 0 V, preventing back-current flow from live buses into a powered-down section. This supports safe hot-swap operation and partial system shutdown - critical in modular industrial controllers and field-replaceable units where subsystems power up/down asynchronously.

What is the significance of VOLP and VOHV specifications for SN74LV367APWRG4?

VOLP (< 0.8 V) and VOHV (> 2.3 V) quantify dynamic ground bounce and output undershoot during switching transitions at 3.3 V. These values indicate the device's ability to suppress noise that could corrupt adjacent signals or cause false triggering in sensitive circuits - making SN74LV367APWRG4 suitable for high-density, mixed-signal PCBs where signal integrity is critical.

Can SN74LV367APWRG4 replace SN74LV367ADR in a design?

Yes, SN74LV367APWRG4 is functionally identical to SN74LV367ADR but in a smaller TSSOP-16 (PW) package versus SOIC-16 (D). Pinout, electrical specs, and timing are fully compatible. Migration requires only layout adjustment for the 5.00 mm × 4.40 mm footprint and reflow profile updates for the thinner PW package - no schematic or firmware changes needed.
