Nexperia USA Inc. 74LVC1G175GV,125

Overview

74LVC1G175GV,125 from Nexperia is a single positive-edge-triggered D-type flip-flop with asynchronous active-low master reset (MR), 6-pin SC-74 (SOT457) package, 1.65 V to 5.5 V supply range, and guaranteed operation from –40 °C to +125 °C - used for data synchronization and state retention in low-power digital control logic, such as sensor interface timing alignment and microcontroller peripheral handshaking.

For engineers reviewing the 74LVC1G175GV,125 datasheet, 74LVC1G175GV,125 pinout, 74LVC1G175GV,125 application, or 74LVC1G175GV,125 equivalent, this device delivers deterministic edge-triggered storage with IOFF power-down protection, Schmitt-trigger inputs for noise immunity, and mixed-voltage interfacing (3.3 V/5 V tolerant inputs), making it suitable for space-constrained industrial I/O expansion and battery-powered logic level translation.

Technical Context

This flip-flop implements synchronous data capture on the LOW-to-HIGH clock transition, with MR operating independently of CP and forcing Q to LOW regardless of clock state. The D input must be stable for ≥1.1 ns (at VCC = 5.5 V) before the rising clock edge to ensure reliable sampling.

Its IOFF circuit disables outputs during power-down, blocking backflow current when VCC = 0 V, while Schmitt-trigger inputs accept slow-rising signals (≤10 ns/V slew rate supported at VCC ≥ 2.7 V), enabling robust operation in noisy or high-impedance signal environments.

FAQ

What is the minimum setup time required for reliable operation at 3.3 V?

At VCC = 3.3 V, the minimum D-to-CP setup time is 1.3 ns (–40 °C to +125 °C range). This ensures predictable latching when D is stable ≥1.3 ns before the rising clock edge. Values are verified per Table 8 in the official Nexperia datasheet Rev. 11, with test conditions including 50 pF load and 500 Ω termination.

Can the 74LVC1G175GV,125 safely interface with 5 V TTL outputs?

Yes - its inputs tolerate up to 5.5 V regardless of VCC setting, and VIH is defined as 0.7 × VCC (min) at 5 V, matching standard TTL HIGH thresholds. This allows direct connection to 5 V TTL sources without level-shifting components, confirmed in Table 6 and Section 1 of the datasheet.

How does the IOFF feature protect the device during partial power-down?

When VCC = 0 V, the IOFF circuit disables all outputs, limiting power-off leakage current to ±2 μA maximum (Table 7). This prevents reverse current flow from powered downstream circuits into the unpowered IC, protecting against latch-up and board-level damage in hot-swap or multi-rail systems.

Is the MR pin truly asynchronous, and what happens if it's asserted mid-clock cycle?

Yes - MR is fully asynchronous and active LOW. When asserted, Q is forced LOW within 0.5 ns (min) regardless of CP state or timing. This behavior is guaranteed across all voltage and temperature conditions per Table 8's MR-to-Q propagation delay specification and Function Table 4.
