Product details
Overview
74HCT2G32DP,125 from Nexperia is a dual 2-input OR gate logic IC in TSSOP8 (SOT505-2) package, operating from 4.5 V to 5.5 V supply, with TTL-compatible inputs, 13 ns typical propagation delay at VCC = 4.5 V, and guaranteed operation from −40 °C to +125 °C - used for level-shifting combinational logic in industrial control I/O conditioning.
For engineers reviewing the 74HCT2G32DP,125 datasheet, 74HCT2G32DP,125 pinout, 74HCT2G32DP,125 application, or 74HCT2G32DP,125 equivalent, this device serves as a low-power, high-noise-immunity dual OR gate with input clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors.
Technical Context
This device implements two independent 2-input OR gates using silicon-gate CMOS technology. Each gate performs Boolean OR logic (Y = A + B) with defined HIGH/LOW input thresholds per JEDEC JESD7A and TTL-level compatibility for 74HCT variant.
It features input clamp diodes referenced to VCC and GND, allowing external current limiting for overvoltage-tolerant input interfacing. Static and dynamic performance is specified across −40 °C to +125 °C, with latch-up immunity >100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input OR gate (Y = A + B per channel) |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with 5 V TTL systems and stable operation under rail variation |
| Propagation Delay (tpd) | 13 ns typ. (VCC = 4.5 V, −40 °C to +125 °C) - enables reliable timing in sub-20 ns combinatorial paths |
| Input Thresholds | VIH = 2.0 V min., VIL = 0.8 V max. - guarantees robust TTL-level recognition without level shifters |
| Output Drive | ±4.0 mA (VOH/VOL @ VCC = 4.5 V) - sufficient to drive standard 74-series fan-out (up to 10 LS-TTL loads) |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and under-hood applications |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces risk of handling damage in automated assembly |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2), 8 leads, body width 3 mm, lead length 0.5 mm, pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First OR gate input A - accepts TTL-level signals; clamped to VCC/GND |
| 2 | 1B | First OR gate input B - identical electrical behavior to Pin 1 |
| 3 | 2Y | Second OR gate output - sinks or sources up to ±4.0 mA at VCC = 4.5 V |
| 4 | GND | Ground reference (0 V) - mandatory return path for all internal currents and noise filtering |
| 5 | 2A | Second OR gate input A - electrically isolated from first gate; shares same VCC/GND |
| 6 | 2B | Second OR gate input B - supports independent logic evaluation alongside Gate 1 |
| 7 | 1Y | First OR gate output - provides active-drive capability compatible with downstream CMOS/TTL loads |
| 8 | VCC | Positive supply (4.5–5.5 V) - powers both gates; decoupling capacitor required near this pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V - eliminates need for external level translation when interfacing legacy 5 V logic |
| Input clamp diodes | Integrated diodes to VCC and GND - enable safe connection of inputs to signals up to 6.0 V using series current-limiting resistors |
| High noise immunity | Typical noise margin >1.2 V (VCC = 5 V) - suppresses false triggering in electrically noisy industrial environments |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive parasitic thyristor activation during transient overstress |
| Wide temperature range | Specified from −40 °C to +125 °C - supports deployment in uncontrolled ambient or thermally stressed PCB locations |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G32DBVR | Lower VCC range (1.65–5.5 V); CMOS inputs; 3.7 ns tpd at 3.3 V | Better suited for mixed-voltage 3.3 V/5 V systems; not TTL-input compatible | Select when interfacing 3.3 V microcontrollers or requiring faster speed at lower supply |
| 74AHC2G32DP,125 | Wider VCC (2.0–5.5 V); CMOS inputs; 5.2 ns tpd at 5 V; higher ICC | Higher speed but consumes more quiescent current; lacks TTL input threshold alignment | Choose for maximum speed in 5 V-only designs where input compatibility with legacy TTL is not required |

FAQ
What is the maximum supply voltage for 74HCT2G32DP,125?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per JEDEC JESD7A. Operation above 5.5 V voids parametric guarantees and risks accelerated degradation, even if within absolute limits. The device is not rated for sustained 6 V operation.
Can 74HCT2G32DP,125 interface directly with 3.3 V microcontroller GPIOs?
No - its TTL-compatible inputs require VIH ≥ 2.0 V minimum, but 3.3 V GPIOs typically output VOH ≈ 3.3 V, which satisfies VIH. However, VOL from the microcontroller (~0.4 V) meets VIL ≤ 0.8 V, so direct connection is electrically valid. No level shifter is needed, but ensure VCC remains at 5 V for correct HCT thresholds.
Does 74HCT2G32DP,125 support hot insertion or live insertion?
No - it lacks explicit hot-swap protection circuitry. Input clamp diodes provide limited overvoltage tolerance only when series current-limiting resistors are used. For true hot-plug operation, external protection (e.g., series FETs, dedicated hot-swap controllers) is required to manage inrush and rail sequencing.
Is there a pin-compatible 74HCT2G32 variant in VSSOP8 package?
Yes - 74HCT2G32DC (SOT765-1, VSSOP8) shares identical logic function, pinout, and electrical specifications, differing only in package dimensions (2.3 mm body width vs. 3 mm for TSSOP8). Marking code is "T32", and thermal derating begins at 99 °C instead of 96 °C.
