Nexperia USA Inc. 74HC165PW-Q100,118

Overview

74HC165PW-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit parallel-in/serial-out shift register in TSSOP16 package, supporting asynchronous parallel load (PL), synchronous serial shift (CP/CE), and dual complementary outputs (Q7/Q7). It operates from -40 °C to +125 °C with CMOS-level inputs, 6 V absolute max supply, and overvoltage-tolerant inputs up to 15 V-enabling high-to-low level shifting in automotive body control modules.

For engineers reviewing the 74HC165PW-Q100 datasheet, 74HC165PW-Q100 pinout, 74HC165PW-Q100 application, or 74HC165PW-Q100 equivalent, key selection criteria include parallel-load latency (14 ns @ 6 V), serial-shift propagation delay (10–15 ns), clock enable timing margins, TTL-compatible alternative (74HCT165PW-Q100), and TSSOP16 thermal derating (8.5 mW/K above 91 °C).

Technical Context

This device implements an 8-stage static shift register with dual-edge-controlled functionality: PL asserts asynchronously to latch D0–D7, while CE and CP jointly govern synchronous serial shifting on rising edges. The architecture supports both parallel capture and serial streaming without internal state corruption during mode transitions.

Input overvoltage tolerance (15 V) enables direct interfacing with 12 V automotive signals into 5 V logic domains. Complementary Q7/Q7 outputs provide noise-immune differential sampling for downstream latches or comparators, with matched propagation delays (Δtpd ≤ 1 ns) across temperature.

FAQ

Can 74HC165PW-Q100 operate reliably at 3.3 V supply?

Yes. The 74HC165PW-Q100 is fully specified from 2.0 V to 6.0 V, with VIH = 1.5 V min and VOL = 0.26 V max at VCC = 3.3 V and IO = 4 mA. Its CMOS inputs ensure clean switching and noise immunity in 3.3 V systems, and it maintains tpd ≤ 24 ns and fmax ≥ 20 MHz across the full -40 °C to +125 °C range.

What is the purpose of the complementary Q7 output?

The Q7 output provides a true inverted copy of the Q7 serial output, with matched propagation delay (≤1 ns skew) and identical drive strength. This enables differential sampling for noise rejection, XOR-based parity generation, or driving complementary inputs on downstream devices like flip-flops or comparators-critical in EMI-prone automotive environments.

How does the overvoltage-tolerant input feature work?

Each input pin integrates internal clamp diodes rated to 15 V, allowing safe interface with 12 V automotive signals without external protection. The clamps conduct only during transient overvoltage events, drawing ≤20 mA peak current (per IEC 60134), and do not affect normal 0–6 V logic operation or DC input leakage (<0.1 μA).

Is the TSSOP16 package suitable for reflow soldering in automotive production?

Yes. The SOT403-1 TSSOP16 package is qualified for lead-free reflow per JEDEC J-STD-020, with maximum peak temperature of 260 °C. Its side-wettable flanks enable automated optical inspection (AOI) of solder fillets, satisfying IATF 16949 process validation requirements for zero-defect automotive assembly.
