Nexperia USA Inc. 74LV165APW,112

Overview

74LV165APW,112 from Nexperia is an 8-bit parallel-in/serial-out CMOS shift register with complementary serial outputs (Q7 and Q7), asynchronous parallel load (PL active LOW), and dual-clock-input gate-OR structure enabling configurable clock enable (CE) functionality. It operates from 2.0 V to 5.5 V, supports -40 °C to +85 °C ambient range, and features IOFF power-down protection. It is used in industrial I/O expansion, LED matrix controllers, and microcontroller GPIO extender circuits.

For engineers reviewing the 74LV165APW,112 datasheet, 74LV165APW,112 pinout, 74LV165APW,112 application, or 74LV165APW,112 equivalent, key selection considerations include propagation delay at 5 V (max 11.5 ns), Schmitt-trigger inputs for noise immunity, 5.5 V tolerant I/O, partial-power-down capability, and TSSOP16 package compatibility with high-density PCB layouts.

Technical Context

The 74LV165APW implements an 8-stage static shift register with independent parallel-load and serial-shift paths controlled by PL and CE/CP logic. Its gate-OR clock input allows either CP or CE to serve as the active-HIGH clock signal while the other acts as active-LOW enable-pin assignments are layout-flexible but require CE transition only when CP is HIGH for deterministic behavior.

Schmitt-trigger inputs ensure robust operation with slow-rising signals, and the IOFF circuit disables outputs during power-down to prevent backflow current. The device delivers complementary Q7/Q7 outputs, enabling direct cascading via Q7→DS without external inverters, supporting synchronous multi-stage serial data chaining.

FAQ

Can the 74LV165APW,112 operate reliably at 2.0 V supply?

Yes. The device is fully specified down to 2.0 V VCC, with guaranteed propagation delay ≤24.0 ns (at 2.5 V), VIH/VIL thresholds scaled to 0.7VCC/0.3VCC, and IOFF leakage <5 μA. Static and dynamic parameters-including 200 ns/V input transition rate tolerance-are validated across the full 2.0–5.5 V range per JEDEC JESD8-5 and JESD8B standards.

What is the correct timing relationship between CE and CP?

The CE input must transition from HIGH to LOW only while CP is held HIGH to avoid metastability. This constraint ensures predictable clock gating behavior. The datasheet specifies a minimum CE recovery time of 4.0 ns after CP goes HIGH (at 5 V), and CE pulse width must exceed 6.0 ns. Violating this timing may cause skipped or duplicated shifts.

Does the 74LV165APW,112 support hot insertion or live swapping?

Yes-its IOFF circuit actively disables outputs when VCC = 0 V, limiting back-current to ±5 μA even with I/O pins biased to 5.5 V. This meets IEC 61000-4-2 Level 4 ESD robustness and enables safe insertion into powered-backplane systems, provided VCC ramp-up sequencing follows manufacturer recommendations in Section 7 of the datasheet.

How does the Schmitt-trigger input improve system reliability?

Schmitt-trigger action provides ≥0.5 V hysteresis on all inputs (PL, CP, CE, DS, D0–D7), rejecting noise spikes up to 100 ns duration and enabling reliable operation with slow-rising signals (e.g., from mechanical switches or long PCB traces). Measured input transition rate tolerance reaches 20 ns/V at 5 V, significantly exceeding standard CMOS input requirements.
