Nexperia USA Inc. 74HC175D-Q100J

Overview

74HC175D-Q100 from Nexperia is an automotive-qualified quad D-type flip-flop with asynchronous master reset, positive-edge clock triggering, and complementary Q/Q̅ outputs per stage. It operates from 2.0 V to 6.0 V, supports -40 °C to +125 °C ambient range, and delivers 35 ns typical propagation delay at 6.0 V (CL = 50 pF). It is used in automotive body control modules for synchronized data latching across multiple sensor inputs.

For engineers reviewing the 74HC175D-Q100 datasheet, 74HC175D-Q100 pinout, 74HC175D-Q100 application, or 74HC175D-Q100 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification, CMOS-level input compatibility, SO16 package footprint, and simultaneous asynchronous reset capability across all four flip-flops.

Technical Context

This device implements four independent edge-triggered D-type storage elements sharing a common clock (CP) and active-low master reset (MR). Each flip-flop captures the logic state at Dn on the LOW-to-HIGH transition of CP, provided setup/hold timing is met. The MR signal forces all Qn outputs LOW regardless of clock state.

It uses standard CMOS silicon technology with TTL-compatible input thresholds only in the 74HCT variant - the 74HC175D-Q100 strictly adheres to CMOS input voltage levels (VIH ≥ 3.15 V at VCC = 4.5 V). Its functional diagram confirms true/complement output pairing (Q0/Q0̅, Q1/Q1̅, etc.) and pin-confirmed 16-pin SO16 layout per SOT109-1.

Compared with 74HC175D-Q100, the 74HCT175D-Q100 offers broader input voltage tolerance but identical automotive qualification, while SN74LV175APWR trades AEC-Q100 compliance for lower-voltage operation and reduced board space - making it unsuitable for under-hood deployment.

FAQ

What is the maximum clock frequency supported by the 74HC175D-Q100?

The 74HC175D-Q100 achieves a maximum operating frequency of 24 MHz at VCC = 6.0 V and CL = 50 pF, based on its 30 ns maximum propagation delay (tpd) and 14 ns minimum clock pulse width (tW). At 4.5 V, fmax drops to 20 MHz due to increased delay; derating applies above 110 °C per its SO16 thermal specification.

Can the 74HC175D-Q100 be used with a 3.3 V supply?

Yes - the 74HC175D-Q100 is fully specified down to 2.0 V, including VIH = 1.5 V (min) and VOL = 0.15 V (max) at VCC = 3.3 V and IO = 4 mA. Its CMOS inputs ensure clean switching with 3.3 V microcontrollers, and its -40 °C to +125 °C rating remains valid across the entire 2.0–6.0 V range.

How does the master reset (MR) interact with the clock input?

The MR input is asynchronous and dominant: a LOW on pin 1 forces all Qn outputs LOW immediately, overriding any clock activity. The reset is not edge-triggered and takes effect within tPHL (max 38 ns at VCC = 4.5 V). Clock transitions during MR assertion have no effect on output state until MR returns HIGH.

Is there a recommended decoupling strategy for this device?

A 100 nF ceramic capacitor placed within 10 mm of pins 8 (GND) and 16 (VCC) is mandatory per Nexperia's layout guidelines. For systems with high di/dt loads, add a 4.7 μF tantalum or polymer capacitor nearby. Avoid shared return paths between VCC/GND and analog sections to prevent coupling of digital switching noise into sensitive circuits.
