Nexperia USA Inc. 74LV17APWJ

Overview

74LV17APWJ from Nexperia is a hex non-inverting buffer with Schmitt-trigger inputs, designed for signal conditioning in noisy or slow-rising digital interfaces. It operates across 2.0 V to 5.5 V supply, delivers ≤10 ns propagation delay at 5 V, supports mixed-voltage translation (e.g., 3.3 V logic driving 5 V loads), and features IOFF partial power-down protection. Used in industrial sensor interface circuits where input signal jitter must be eliminated before microcontroller sampling.

For engineers reviewing the 74LV17APWJ datasheet, 74LV17APWJ pinout, 74LV17APWJ application, or 74LV17APWJ equivalent, this page provides verified pin functions, Schmitt threshold values (VT+ = 3.5 V / VT− = 1.5 V at VCC = 5 V), IOFF leakage (<0.5 μA), temperature range (−40 °C to +125 °C), and real-world use cases in level-shifting and noise-immune signal routing.

Technical Context

The 74LV17A implements six independent Schmitt-trigger input buffers with non-inverting logic, each featuring hysteresis (VH = 0.5 V at VCC = 5 V) to reject noise on slow edges. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-swap or partial system power-down.

Input overvoltage tolerance up to 7.0 V enables safe interfacing between disparate voltage domains (e.g., 5 V sensors into 3.3 V MCU GPIO). Static thresholds are tightly specified: VT+ = 3.5 V and VT− = 1.5 V at VCC = 5.0 V, ensuring consistent switching points across −40 °C to +125 °C.

FAQ

What is the maximum input voltage the 74LV17APWJ can tolerate when VCC = 3.3 V?

The 74LV17APWJ tolerates input voltages up to +7.0 V regardless of VCC level, per Absolute Maximum Ratings (Table 4). This allows direct connection of 5 V sensor outputs to a 3.3 V-powered device without external clamping diodes or resistive dividers - a key enabler for mixed-voltage system design.

Does the 74LV17APWJ support true bidirectional level translation?

No - the 74LV17APWJ is a unidirectional buffer (input → output only). While its overvoltage-tolerant inputs accept 5 V signals when powered from 3.3 V, the outputs swing only between GND and VCC (3.3 V), so it cannot drive 5 V logic high levels. For true bidirectional translation, a dedicated bus switch or dual-supply translator is required.

How does the IOFF feature behave during partial power-down?

When VCC = 0 V, the IOFF circuit disables all six outputs, limiting output leakage to <0.5 μA (Table 6). This prevents current backflow from live downstream circuits (e.g., 5 V buses) into the unpowered IC, protecting both the 74LV17APWJ and connected devices during hot-swap or staged power sequencing.

Can the 74LV17APWJ replace standard 74HC17 buffers in existing designs?

Yes - pin-compatible with 74HC17 and 74HCT17 in TSSOP14 packages, but with critical improvements: wider 2.0–5.5 V supply range (vs HC's 2.0–6.0 V), guaranteed Schmitt thresholds across temperature, IOFF support, and superior ESD ratings. No layout change needed; verify timing margins using the 10 ns max tpd spec at target VCC and load.
