Nexperia USA Inc. 74HC74PW-Q100,118

Overview

74HC74PW-Q100 from Nexperia is an automotive-qualified dual positive-edge-triggered D-type flip-flop with independent asynchronous set (nSD) and reset (nRD) inputs, complementary Q/nQ outputs per section, Schmitt-trigger clock input for robust edge detection, and operation over -40 °C to +125 °C. It stores data on LOW-to-HIGH clock transitions with 14 ns propagation delay at VCC = 6.0 V and supports CMOS-level inputs. It is used in automotive body control modules for synchronized signal latching and state retention.

For engineers reviewing the 74HC74PW-Q100 datasheet, 74HC74PW-Q100 pinout, 74HC74PW-Q100 application, or 74HC74PW-Q100 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification, TSSOP14 package with 4.4 mm body width, dual independent flip-flop architecture with asynchronous controls, and compatibility with 2.0–6.0 V supply rails.

Technical Context

This device implements two identical, electrically isolated D-type flip-flops in a single monolithic IC. Each section features separate data (nD), clock (nCP), active-low set (nSD), and active-low reset (nRD) terminals, enabling independent control of Q and nQ outputs without inter-stage coupling.

The Schmitt-trigger action on nCP ensures reliable triggering even with slow-rising clock signals, while internal clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. All inputs meet JEDEC Standard No. 7A and support operation across industrial and extended automotive temperature ranges.

FAQ

What is the maximum clock frequency supported by the 74HC74PW-Q100?

The 74HC74PW-Q100 supports a maximum clock frequency of 82 MHz at VCC = 6.0 V and Tamb = 25 °C, with derating to 24 MHz at +125 °C ambient. This is measured under CL = 50 pF load conditions and assumes proper setup/hold timing compliance - actual system-level frequency depends on PCB routing, fanout, and supply stability.

Can the 74HC74PW-Q100 operate reliably at 3.3 V supply?

Yes - the 74HC74PW-Q100 is fully specified from 2.0 V to 6.0 V, including 3.3 V operation. At VCC = 3.3 V, typical propagation delay is ~25 ns and VIH is 2.31 V minimum, ensuring compatibility with standard 3.3 V CMOS logic families while maintaining AEC-Q100 Grade 1 performance across -40 °C to +125 °C.

Does the TSSOP14 package (SOT402-1) support automated optical inspection (AOI)?

No - unlike the DHVQFN14 (SOT762-1) variant, the TSSOP14 package does not feature side-wettable flanks. AOI capability is exclusive to the DHVQFN14 version; the TSSOP14 relies on standard X-ray or electrical test for solder joint verification in automotive production lines.

How does the Schmitt-trigger clock input improve system robustness?

The Schmitt-trigger on nCP provides hysteresis (typ. 0.3 V at VCC = 4.5 V), allowing reliable edge detection on noisy or slowly rising clock signals - such as those from mechanical switches, LIN bus-derived clocks, or RC-generated timing - without external debouncing or conditioning circuitry, reducing BOM count and board space in automotive modules.
