Nexperia USA Inc. 74LVC2G74GM,125

Overview

74LVC2G74GM,125 from Nexperia is a single positive-edge-triggered D-type flip-flop with asynchronous set (SD) and reset (RD) inputs, complementary Q and Q̅ outputs, 1.65 V to 5.5 V supply range, ±24 mA output drive at VCC = 3.0 V, and IOFF partial power-down support - used in level translation and synchronous logic control in mixed-voltage digital systems.

For engineers reviewing the 74LVC2G74GM,125 datasheet, 74LVC2G74GM,125 pinout, 74LVC2G74GM,125 application, or 74LVC2G74GM,125 equivalent, this device serves as a compact, rail-to-rail voltage-tolerant storage element for clock-synchronized data latching, bus isolation, and 3.3 V/5 V interface bridging in space-constrained industrial and automotive control modules.

Technical Context

This flip-flop implements edge-triggered synchronous storage with independent active-low asynchronous controls: SD and RD override clocked operation to force Q = H or Q = L regardless of CP state. Its Schmitt-trigger inputs tolerate slow-rising signals and improve noise immunity in noisy environments.

The IOFF circuit disables outputs when VCC = 0 V, blocking backflow current during partial power-down - critical for hot-swap and multi-rail system designs. Input overvoltage tolerance up to 5.5 V enables direct interfacing with 5 V TTL logic while powered from 1.65–3.3 V supplies.

FAQ

Does 74LVC2G74GM,125 support 5 V input signals while operating at 1.8 V VCC?

Yes. All inputs are overvoltage tolerant up to 5.5 V regardless of VCC level, enabling direct connection to 5 V TTL or CMOS outputs without external level-shifting components. This is confirmed in Section 2 (Features and benefits) and Table 7 (Recommended operating conditions) of the datasheet.

What is the minimum pulse width required on CP, SD, or RD inputs?

The minimum CP pulse width is 2.0 ns at VCC = 4.5–5.5 V (Table 9). For SD and RD, minimum pulse width is 1.0 ns under same conditions. These values ensure reliable edge detection and asynchronous assertion across the full −40 °C to +125 °C temperature range.

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

When VCC drops to 0 V, the IOFF circuit actively disables all outputs, limiting output leakage to ±2 μA maximum (Table 8). This prevents back-current flow from powered downstream circuits into the unpowered IC - critical for safe hot-swap and multi-rail power sequencing.

Can 74LVC2G74GM,125 replace 74LVC2G74DP in existing TSSOP8 layouts?

No. The 74LVC2G74GM,125 uses XQFN8 (SOT902-2), a 1.4 × 1.2 mm no-lead package with wettable flanks, whereas 74LVC2G74DP uses TSSOP8 (SOT505-2), a 3 mm-wide leaded package. Footprint, soldering profile, and rework methodology differ significantly - redesign is required.
