Nexperia USA Inc. 74LVC2G32DP,125

Overview

74LVC2G32DP from Nexperia is a dual 2-input OR gate logic IC in TSSOP8 package, operating from 1.65 V to 5.5 V supply, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and 5 V-tolerant inputs/outputs. It enables level translation between 3.3 V and 5 V domains in compact digital interface circuits.

For engineers reviewing the 74LVC2G32DP datasheet, 74LVC2G32DP pinout, 74LVC2G32DP application, or 74LVC2G32DP equivalent, this device supports mixed-voltage system interfacing, low-power portable logic, and robust signal conditioning where input rise/fall time tolerance and backflow current prevention are critical.

Technical Context

The 74LVC2G32DP implements two independent OR gates with Schmitt-trigger inputs, enabling reliable operation with slow or noisy input signals. Its IOFF circuit actively disables outputs during power-down, blocking destructive backflow current when VCC = 0 V.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V), and supports ambient temperatures from –40 °C to +125 °C - validated for industrial-grade reliability.

FAQ

Can the 74LVC2G32DP be used to interface a 5 V microcontroller GPIO with a 3.3 V FPGA input?

Yes - its 5 V-tolerant inputs accept 5 V logic highs while powered from 3.3 V VCC, and its outputs swing rail-to-rail (0 V to 3.3 V), matching FPGA input thresholds. No external level shifter is required, provided the FPGA input is 3.3 V tolerant. The Schmitt-trigger inputs further improve noise rejection on long traces.

Does the IOFF feature work when only one supply rail is powered down?

Yes - IOFF activates whenever VCC = 0 V, regardless of input/output voltage states. With VCC unpowered, the outputs enter high-impedance mode and leakage remains ≤±2 μA, preventing current flow from live 5 V inputs into the unpowered IC or adjacent circuitry - critical for hot-swap and partial-system shutdown.

What is the maximum capacitive load the 74LVC2G32DP can drive at 10 MHz with 3.3 V supply?

At VCC = 3.3 V and 10 MHz toggle rate, the device can reliably drive up to 50 pF total load (including trace and input capacitance) while maintaining <4 ns propagation delay and <0.55 V VOL. This assumes proper PCB layout with local 100 nF decoupling and ground plane - exceeding 50 pF increases delay and may cause marginal timing in synchronous systems.

Is the 74LVC2G32DP pin-compatible with other dual OR gate variants in TSSOP8?

Yes - the 74LVC2G32DP shares identical pinout (SOT505-2) with 74LVC2G32DC, 74AUP2G32DC, and SN74LVC2G32DBVR. All follow the same 1A-VCC-1B-1Y-2Y-2B-GND-2A sequence. However, electrical differences (e.g., voltage range, IOFF, temp grade) require validation before drop-in replacement.
