Nexperia USA Inc. 74LVC1G125GV/DG,12

Overview

74LVC1G125GV/DG,12 from Nexperia is a single non-inverting 3-state buffer with 5.5 V tolerant inputs, operating from 1.65 V to 5.5 V supply, featuring 4 ns propagation delay at 3.3 V and ±24 mA output drive capability. It serves as a level-translating bus interface device in low-voltage embedded control systems.

For engineers reviewing the 74LVC1G125GV/DG,12 datasheet, 74LVC1G125GV/DG,12 pinout, 74LVC1G125GV/DG,12 application, or 74LVC1G125GV/DG,12 equivalent, key selection criteria include input voltage tolerance, output drive strength, propagation delay consistency across V_CC, and guaranteed 3-state leakage performance under partial power-down conditions.

Technical Context

This buffer implements a CMOS-based Schmitt-trigger input stage for noise immunity and supports mixed-voltage system interfacing via 5.5 V tolerant inputs while powered from as low as 1.65 V. Its 3-state control logic is active-low (OE̅), with output disabled when OE̅ = HIGH.

The device complies with JEDEC standard JESD8-12A for 1.8 V/2.5 V/3.3 V/5 V I/O interfaces and meets AEC-Q100 Grade 1 reliability requirements for automotive applications. Output clamping diodes are absent, requiring external protection if used in hot-swap environments.

FAQ

Is 74LVC1G125GV/DG,12 compatible with 1.2 V input signals?

No. The minimum high-level input voltage (V_IH) is 0.7 × V_CC, so at V_CC = 1.65 V, V_IH = 1.155 V. A 1.2 V signal meets this threshold only if V_CC ≥ 1.71 V. Below that, the input may not register as logic HIGH reliably.

Can OE̅ be left floating during operation?

No. OE̅ has no internal pull-up or pull-down. Floating OE̅ risks undefined output state and increased EMI due to metastability. External pull-down (to GND) is required for default-disabled operation; pull-up (to V_CC) for default-enabled.

Does this device support hot insertion?

No. It lacks input clamping diodes and I_OFF protection. Applying input voltage before V_CC can forward-bias internal ESD structures, causing latch-up or permanent damage. Power sequencing must follow V_CC before any input signal.

What is the maximum capacitive load this buffer can drive reliably?

At 3.3 V supply, the device maintains ≤4 ns t_PD and monotonic edges up to 50 pF. Driving >70 pF increases rise/fall times nonlinearly and may cause overshoot exceeding 0.3 V, risking false triggering in downstream receivers.
