Product details
Overview
74ABT32PW,118 from Nexperia is a quad 2-input OR gate logic IC in TSSOP14 package, operating from 4.5 V to 5.5 V supply, with IOFF-enabled partial power-down protection, 2.3 ns typical propagation delay (tPLH/tPHL), and -40 °C to +85 °C industrial temperature range. It serves as a high-speed level-shifting combinatorial logic element in bus interface and control signal routing.
For engineers reviewing the 74ABT32PW,118 datasheet, 74ABT32PW,118 pinout, 74ABT32PW,118 application, or 74ABT32PW,118 equivalent, this device is selected for TTL-compatible 5 V logic systems requiring low skew (<0.5 ns), latch-up immunity (>500 mA), and robust ESD resilience (HBM >2000 V, CDM >1000 V).
Technical Context
The 74ABT32PW,118 implements four independent OR gates using BiCMOS process technology, enabling TTL-level input compatibility and high-current drive capability (IOL = 20 mA, IOH = -15 mA). Its IOFF circuitry actively disables outputs during VCC = 0 V, blocking backflow current and supporting hot-swap and partial power-down system architectures.
Dynamic performance is characterized by matched propagation delays across all four channels (tPLH/tPHL ≤ 3.8 ns over full temperature range) and guaranteed output skew ≤ 0.5 ns, ensuring deterministic timing in synchronous control paths and address decoding applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation across standard 5 V rail tolerances and brown-out conditions. |
| Propagation Delay | 2.3 ns typ (tPLH/tPHL at VCC = 5.0 V) - Enables sub-400 MHz clock domain interfacing with minimal timing budget impact. |
| Output Drive | IOL = 20 mA / IOH = -15 mA - Directly drives multiple TTL inputs or small capacitive loads without external buffers. |
| IOFF Leakage | ±100 μA max at VCC = 0 V - Prevents destructive backfeed current when powered down in mixed-voltage systems. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Meets industrial handling requirements without additional board-level protection. |
| Operating Temp | -40 °C to +85 °C - Qualified for extended industrial environments including factory automation and telecom infrastructure. |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V - Guarantees reliable recognition of TTL and CMOS 5 V logic levels. |
Pinout & Package
TSSOP14 package (SOT402-1): 4.4 mm body width, 0.65 mm lead pitch, 1.20 mm max height; optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input per OR gate - Accepts TTL/CMOS logic signals; internally terminated to VCC/GND via clamping diodes. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input per OR gate - Dual-input OR function requires both A and B asserted HIGH for Y HIGH. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Active-HIGH OR output - Sinks up to 20 mA or sources up to 15 mA; supports wired-OR configurations only if externally pulled. |
| 7 | GND | Ground reference - All voltage measurements and current paths referenced to this pin; must be low-impedance connection. |
| 14 | VCC | Positive supply - Powers internal BiCMOS circuitry; requires local 100 nF decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-Down | Outputs enter high-impedance state at VCC = 0 V, eliminating backflow current in hot-plug or sleep-mode subsystems. |
| BiCMOS Output Stage | Combines bipolar speed and MOS input impedance, delivering 2.3 ns propagation with 20 mA sink capability at 5 V. |
| Latch-Up Immunity | Exceeds 500 mA per JESD78B Class II Level A - Survives transient overcurrent events without destructive latch-up. |
| Low Output Skew | ≤0.5 ns max between any two outputs - Enables simultaneous assertion of multiple control signals in timing-critical paths. |
| TTL Input Compatibility | VIL ≤ 0.8 V and VIH ≥ 2.0 V at VCC = 4.5–5.5 V - Interoperates directly with legacy 74LS and microcontroller GPIO without level shifters. |
Applications
| Industrial Bus Interface | Microcontroller I/O Expansion |
|---|---|
|
Use Scenario: Isolating and merging interrupt request lines from multiple sensors on an RS-485 fieldbus node. IC Role / Device Role / Timing Role: Combinatorial OR gate aggregating active-HIGH IRQ signals into a single MCU interrupt input. Use Value: Eliminates need for discrete diode-OR networks while guaranteeing sub-4 ns delay matching across all four channels. |

IC Role / Device Role / Timing Role: Logic-level translation and signal conditioning for peripheral enable/control lines. Use Value: Provides TTL-compatible 5 V drive strength (20 mA sink) to directly activate relays or LED drivers without buffer stages. |
| Power Sequencing Control | Digital Test Equipment |
|
Use Scenario: Generating "ALL_RAILS_READY" status flag from individual DC/DC converter OK signals. IC Role / Device Role / Timing Role: Active-HIGH OR function monitoring four independent power-good outputs. Use Value: IOFF feature ensures no backfeed occurs if main logic rail powers down before auxiliary supplies during fault recovery. |
Use Scenario: Implementing programmable test pattern generation in boundary-scan controller logic. IC Role / Device Role / Timing Role: Glue logic for combining scan-enable, clock-gate, and reset signals. Use Value: Matched propagation delays (<3.8 ns) and <0.5 ns skew preserve setup/hold timing margins in high-speed digital test vectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT32DBR | SSOP14 package (SOT337-1); identical electrical specs but 5.3 mm body width and 0.635 mm pitch. | Less suitable for ultra-high-density boards due to larger footprint and non-JEDEC-aligned pin spacing. | Select when legacy SSOP footprint compatibility is required and board space permits. |
| 74LVC32APW,118 | Lower VCC range (1.65–3.6 V); CMOS-only process; 3.7 ns max tPD at 3.3 V; no IOFF support. | Not usable in 5 V systems or partial-power-down designs; lacks latch-up immunity rating. | Choose only for 3.3 V-only applications where cost and power efficiency outweigh robustness requirements. |
Compared with SN74ABT32DBR and 74LVC32APW,118, the 74ABT32PW,118 uniquely balances 5 V TTL interoperability, IOFF-enabled system-level power management, and JEDEC-standard TSSOP14 packaging for modern industrial PCBs.

FAQ
Does 74ABT32PW,118 support mixed-voltage operation between input and output rails?
No. The device operates strictly from a single VCC supply (4.5–5.5 V). Inputs and outputs are referenced to this rail; no dual-supply or level-shifting capability is provided. IOFF only activates when VCC = 0 V, not during intermediate voltage states.
Can 74ABT32PW,118 outputs be safely wired together for a shared-bus OR function?
No. Outputs are push-pull and not designed for wired-OR. Connecting outputs risks contention and excessive current flow. For bus applications, use open-collector/drain devices or external pull-up resistors with appropriate current limiting.
What is the maximum capacitive load the 74ABT32PW,118 can drive while maintaining specified propagation delay?
The datasheet specifies dynamic characteristics with CL = 50 pF (Table 8). Driving loads >50 pF increases tPLH/tPHL nonlinearly; for loads up to 100 pF, expect ~15–20% delay increase. Maintain CL ≤ 50 pF for guaranteed timing compliance.
Is 74ABT32PW,118 qualified for automotive applications?
No. It is rated for industrial temperature range (-40 °C to +85 °C) and carries no AEC-Q100 qualification. Nexperia explicitly states non-automotive qualification in its legal disclaimers; automotive use requires explicit automotive-grade variants like 74ABT32-Q100.
