Nexperia USA Inc. 74LV164PW-Q100J

Overview

74LV164PW-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit serial-in/parallel-out shift register with dual gated data inputs (DSA/DSB), asynchronous master reset (MR), and edge-triggered clock (CP). It operates from 1.0 V to 5.5 V, supports TTL-level inputs at 2.7–3.6 V, and delivers 8 parallel outputs (Q0–Q7) for automotive lighting control, display drivers, and I/O expansion. Its TSSOP14 package enables high-density PCB layouts in engine control units and body electronics.

For engineers reviewing the 74LV164PW-Q100 datasheet, 74LV164PW-Q100 pinout, 74LV164PW-Q100 application, or 74LV164PW-Q100 equivalent, key selection criteria include its wide supply range (1.0–5.5 V), guaranteed operation at −40 °C to +125 °C, asynchronous reset behavior, propagation delay of 12 ns at 3.3 V/15 pF, and compatibility with legacy 74-series logic timing margins.

Technical Context

This shift register implements an 8-stage edge-triggered serial-to-parallel conversion architecture where Q0 = DSA ∧ DSB sampled one setup time before each LOW-to-HIGH CP transition. Data entry is controlled by the logical AND of DSA and DSB, enabling gated serial input functionality without external logic.

The device features a fully asynchronous active-low master reset (MR) that forces all eight outputs (Q0–Q7) LOW regardless of clock state or data inputs. Its static and dynamic characteristics are specified across two temperature ranges (−40 °C to +85 °C and −40 °C to +125 °C), with propagation delays as low as 12 ns and maximum clock frequency up to 100 MHz at 5.0 V.

FAQ

What is the minimum supply voltage required for guaranteed operation of the 74LV164PW-Q100?

The 74LV164PW-Q100 is guaranteed to operate down to 1.0 V, with static characteristics validated from 1.2 V and functional operation confirmed at 1.0 V when inputs are driven to GND or VCC. This enables direct use with ultra-low-power microcontrollers and battery-backed systems where supply may dip below 1.2 V during brownout conditions.

How does the dual data input (DSA/DSB) architecture affect timing behavior?

DSA and DSB are logically ANDed to generate the effective serial input to Q0, with the result sampled one setup time before each rising CP edge. This means both inputs must be stable for tsu = 5 ns (min) prior to the clock edge; violating this causes metastability in Q0, propagating erroneous bits through subsequent stages - requiring careful synchronization in FPGA or MCU firmware.

Can the master reset (MR) be used as a synchronous clear in timing-critical applications?

No - MR is purely asynchronous and overrides all clock and data activity. When asserted LOW, it forces Q0–Q7 to LOW within tPHL = 12 ns (max at 3.3 V), independent of CP state. For synchronous reset behavior, external logic must gate MR with CP or use a different shift register with dedicated synchronous clear.

Is the TSSOP14 package (SOT402-1) compatible with reflow profiles for lead-free assembly?

Yes - the SOT402-1 package is qualified for standard Pb-free reflow profiles (J-STD-020 Rev. E), with peak temperature up to 260 °C and 60-second duration above 217 °C. Its side-wettable flanks are specifically engineered to pass automated optical inspection after lead-free soldering, meeting IPC-A-610 Class 3 requirements for automotive production.
