Nexperia USA Inc. 74LVC1G175GW,125

Overview

74LVC1G175GW,125 from Nexperia is a single positive-edge-triggered D-type flip-flop with asynchronous active-low master reset (MR), 6-pin TSSOP6 package, 1.65 V to 5.5 V supply range, and guaranteed operation from –40 °C to +125 °C. It transfers data from D to Q on LOW-to-HIGH clock transitions, supports mixed-voltage interfacing (3.3 V/5 V), and features IOFF partial power-down protection for backflow current prevention in powered-down systems.

For engineers reviewing the 74LVC1G175GW,125 datasheet, 74LVC1G175GW,125 pinout, 74LVC1G175GW,125 application, or 74LVC1G175GW,125 equivalent, this device serves as a compact, low-power edge-triggered storage element in timing-critical signal conditioning, level-shifting I/O interfaces, and reset-synchronized control logic where deterministic setup/hold timing and robust noise immunity are required.

Technical Context

This flip-flop implements synchronous data capture with asynchronous reset: MR forces Q LOW independently of CP, while valid D input must be stable ≥1.1 ns before the CP rising edge at VCC = 5.5 V. Schmitt-trigger inputs tolerate slow-rising signals, enabling direct connection to mechanical switches or RC-filtered sources without external debouncing.

Its IOFF circuit disables outputs when VCC = 0 V, blocking damaging current flow in hot-swap or multi-rail power sequencing scenarios. Overvoltage-tolerant inputs (up to 5.5 V) allow safe interfacing with 5 V logic even when operating at 1.65 V, eliminating level translators in mixed-supply designs.

FAQ

What is the minimum pulse width required on the MR pin to ensure reliable reset?

The MR pin requires a minimum LOW pulse width of 1.0 ns at VCC = 5.5 V to guarantee propagation to Q output. At lower voltages (e.g., 1.65 V), the minimum widens to 1.9 ns. This specification ensures deterministic reset behavior across the full operating voltage and temperature range, verified per JEDEC JESD8-7 compliance.

Can the 74LVC1G175GW,125 interface directly with 5 V TTL outputs?

Yes - its inputs tolerate up to 5.5 V regardless of VCC level, and its output VOH reaches 3.8 V at VCC = 4.5 V with 32 mA sink, meeting TTL VIH (≥2.0 V) and VIL (≤0.8 V) thresholds. No level-shifting circuitry is needed when driving or receiving from standard 5 V TTL devices.

How does the IOFF feature behave during partial power-down?

When VCC drops to 0 V, the IOFF circuit actively disables both Q output and internal input buffers, limiting I/O leakage to ±2 μA. This prevents current backflow from powered sections (e.g., 5 V I²C bus) into the unpowered device, protecting upstream drivers and maintaining bus integrity during hot-swap or staged power cycling.

Is the 74LVC1G175GW,125 qualified for automotive applications?

While not AEC-Q100 qualified, the 74LVC1G175GW,125 is specified for –40 °C to +125 °C operation and packaged in moisture-sensitive level 1 (MSL1) TSSOP6. It is widely deployed in non-safety-critical automotive subsystems such as infotainment I/O expansion and body control modules where full qualification is not mandated.
