Nexperia USA Inc. 74LV165APW-Q100J

Overview

74LV165APW-Q100 from Nexperia is an automotive-grade 8-bit parallel-in/serial-out shift register with complementary Q7/Q7 outputs, asynchronous parallel load (PL active LOW), synchronous serial shift on CP rising edge, and dual-input clock gate (CP/CE) enabling flexible clock enable routing. It operates from 2.0 V to 5.5 V across −40 °C to +85 °C and supports TTL-level interfacing in automotive body control modules for LED matrix expansion.

For engineers reviewing the 74LV165APW-Q100 datasheet, 74LV165APW-Q100 pinout, 74LV165APW-Q100 application, or 74LV165APW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 3 qualification, IOFF power-down protection, Schmitt-trigger inputs for noise immunity, and TSSOP16 package compatibility with high-density PCB layouts.

Technical Context

This device implements an 8-stage static CMOS shift register with dual-mode input control: PL asserts asynchronous parallel load of D0–D7, while CE and CP form a gated clock structure allowing either pin to serve as active-LOW clock enable. The output stage provides true and complemented serial outputs (Q7 and Q7) for differential signaling or fanout flexibility.

Its IOFF circuitry disables outputs during power-down to prevent backflow current, and Schmitt-trigger inputs tolerate slow-rising signals-critical for noisy automotive environments. All logic thresholds scale with VCC (VIH = 0.7VCC, VIL = 0.3VCC), ensuring robust operation across the full 2.0–5.5 V supply range.

FAQ

Can 74LV165APW-Q100 operate reliably at 2.0 V supply?

Yes. The device is fully specified down to 2.0 V supply per Table 5, with guaranteed VIH = 1.5 V (min) and VOL = 0.55 V (max) at 2.0 V. Propagation delay increases to 22 ns typical, but all timing parameters remain valid across the full 2.0–5.5 V range.

What happens to outputs during power-down (VCC = 0 V)?

The IOFF circuitry actively disables all outputs when VCC drops to 0 V, limiting output leakage to ±5 μA maximum (Table 9). This prevents back-current flow into powered sections of the system, satisfying ISO 16750-2 power-off safety requirements.

Is CE required to be held HIGH before toggling CP?

No - CE and CP are logically OR'd. However, the datasheet specifies that CE must transition from HIGH to LOW only while CP is HIGH to ensure predictable behavior (Section 1). Violating this causes metastability in the clock gate, potentially skipping or duplicating shifts.

How does the Schmitt-trigger input improve noise immunity?

Schmitt-trigger inputs provide ≥0.3 V hysteresis at 5 V supply, meaning VIH and VIL differ by that margin. This prevents multiple toggles on slow or noisy edges - for example, a 100 ns rise time signal with 300 mV ripple will not cause false triggering, unlike standard CMOS inputs.
