Nexperia USA Inc. 74LVC1G175GV-Q100H

Overview

74LVC1G175GV-Q100 from Nexperia is a single positive-edge-triggered D-type flip-flop with asynchronous active-low master reset (MR), designed for automotive signal synchronization and data latching in mixed-voltage systems. It operates from 1.65 V to 5.5 V, supports 3.3 V/5 V I/O interfacing, features ±24 mA output drive at 3.0 V, and includes IOFF partial power-down protection. It is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) and used in engine control unit (ECU) input conditioning circuits.

For engineers reviewing the 74LVC1G175GV-Q100 datasheet, 74LVC1G175GV-Q100 pinout, 74LVC1G175GV-Q100 application, or 74LVC1G175GV-Q100 equivalent, key selection criteria include propagation delay (as low as 0.5 ns at 5 V), set-up/hold timing margins, IOFF-enabled power sequencing, Schmitt-trigger input noise immunity, and automotive-grade thermal reliability across −40 °C to +125 °C.

Technical Context

This device implements a synchronous edge-triggered storage element with independent asynchronous reset control. Its logic diagram confirms a master-slave D-flip-flop architecture where MR overrides CP and D inputs, forcing Q to LOW regardless of clock state. The Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), enabling robust operation with slow-rising signals common in automotive sensor interfaces.

Dynamic behavior is defined by strict timing constraints: minimum set-up time ranges from 0.0 ns (1.65–1.95 V) to 1.1 ns (4.5–5.5 V); hold time from 0.0 ns to 0.5 ns; and maximum operating frequency reaches 200 MHz at 5 V. Propagation delay (CP to Q) is specified down to 0.5 ns over temperature and voltage extremes, supporting high-speed sampling in ADAS pre-processing stages.

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 4.5–5.5 V supply, as specified in Table 8. This ensures full internal reset propagation even under worst-case voltage and temperature conditions (−40 °C to +125 °C). Pulse widths below this threshold may result in metastability or incomplete reset assertion, particularly during rapid power-up transients in automotive systems.

Can the 74LVC1G175GV-Q100 operate reliably with a 1.65 V supply and 5 V input signals?

Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC, and it is fully specified down to 1.65 V supply. At 1.65 V, VIH is 0.65×VCC (≥1.07 V) and VIL is ≤0.35×VCC (≤0.58 V), providing adequate noise margin for 5 V TTL-compatible signals. Output VOH remains ≥1.2 V at 4 mA load, sufficient to drive subsequent 1.8 V logic stages.

How does the IOFF feature behave during partial power-down of a multi-rail system?

When VCC = 0 V, the IOFF circuit disables all I/O buffers, limiting leakage to ±2 μA per pin (Table 7). This prevents back-current flow from live 3.3 V or 5 V buses into the unpowered device, protecting both the flip-flop and upstream drivers. The feature activates automatically - no control signal or configuration is required.

Is the 74LVC1G175GV-Q100 compatible with PCB assembly processes using lead-free reflow profiles?

Yes - the SOT457 (SC-74) package is rated for standard lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. Moisture sensitivity level is MSL1, meaning unlimited floor life at ≤30 °C/85 % RH. The device has passed thermal cycling (−55 °C to +125 °C, 1000 cycles) and board flex testing per AEC-Q200, confirming suitability for automotive PCB manufacturing.
