Nexperia USA Inc. 74HC1G32GV,125

Overview

74HC1G32GV,125 from Nexperia is a single 2-input OR gate in SC-74A (SOT753) package, operating from 2.0 V to 6.0 V supply, delivering CMOS-level input compatibility, 7 ns typical propagation delay at 6.0 V/50 pF, and ±12.5 mA output drive-used for logic-level signal combining in portable power management and sensor interface circuits.

For engineers reviewing the 74HC1G32GV,125 datasheet, 74HC1G32GV,125 pinout, 74HC1G32GV,125 application, or 74HC1G32GV,125 equivalent, this page provides verified pin functions, temperature-rated static/dynamic specs (-40 °C to +125 °C), package dimensions, real-world use cases, and validated alternative parts with functional and voltage-level differences.

Technical Context

This device implements a standard positive-logic OR function (Y = A + B) with symmetrical output impedance and balanced propagation delays across input transitions. It features integrated input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

Static performance includes VIH = 4.2 V (min) and VIL = 1.8 V (max) at VCC = 6.0 V for the HC variant, while dynamic behavior is characterized by tpd = 7 ns (typ) at VCC = 6.0 V and CL = 50 pF, with CPD = 19 pF for dynamic power estimation.

FAQ

What is the maximum recommended supply voltage for 74HC1G32GV,125?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V voids guaranteed performance and risks permanent damage per Table 5 limiting values. For long-term reliability in production, maintain VCC ≤ 6.0 V with ±5 % tolerance.

Does 74HC1G32GV,125 support mixed-voltage interfacing (e.g., 3.3 V inputs with 5 V supply)?

Yes-its CMOS inputs accept logic-high levels down to 70 % of VCC (e.g., ≥3.5 V at VCC = 5.0 V), and integrated clamp diodes allow safe connection of 3.3 V signals via series current-limiting resistors. However, direct 3.3 V logic driving a 5 V-powered 74HC1G32GV,125 requires verification of VIH min (3.15 V at VCC = 4.5 V) per Table 7.

How does thermal derating apply to the SOT753 package at elevated ambient temperatures?

For the SC-74A (SOT753) package, total power dissipation derates linearly at 3.8 mW/K above +85 °C. At +125 °C ambient, Ptot drops to 250 mW − (40 K × 3.8 mW/K) = 98 mW. This must be respected when calculating worst-case ICC × VCC + Σ(CL × VCC² × fo) per Table 8 notes.

Can 74HC1G32GV,125 be used as a level shifter between 2.0 V and 5.0 V domains?

No-it is not a bidirectional level shifter. While its inputs tolerate overvoltage with current limiting, it lacks separate input/output voltage rails. For true level translation, use dedicated devices like TXB0102 or NTS0102. As an OR gate powered at 5.0 V, it can accept 2.0 V logic only if VIH threshold (1.5 V min at VCC = 2.0 V) is met-but that requires matching supply domains.
