Product details
Overview
74ABT32PW from Nexperia is a quad 2-input OR gate in TSSOP14 package, operating at 4.5 V to 5.5 V supply, with propagation delays as low as 1.0 ns (tPLH/tPHL), IOFF-enabled partial power-down protection, and guaranteed operation from –40 °C to +85 °C. It interfaces directly with TTL logic levels and delivers 20 mA sink current per output for robust signal routing in digital control planes.
For engineers reviewing the 74ABT32PW datasheet, 74ABT32PW pinout, 74ABT32PW application, or 74ABT32PW equivalent, this device is selected for high-speed combinational logic in industrial PLC I/O modules, legacy bus interface buffers, and power-aware FPGA companion logic where backflow current prevention during partial shutdown is required.
Technical Context
The 74ABT32PW implements four independent OR gates using BiCMOS technology, combining bipolar speed with CMOS input impedance. Each gate accepts two inputs (nA/nB) and drives one output (nY) with rail-to-rail swing referenced to VCC and GND.
Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting power-off leakage to ±100 μA while blocking reverse current flow - critical for hot-swap and multi-rail system designs. Output skew is guaranteed ≤0.5 ns across all four channels under same-direction switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-voltage logic domains |
| Propagation Delay | 1.0–3.8 ns (tPLH/tPHL) - enables sub-4 ns gate-level timing in synchronous control paths |
| Output Drive | 20 mA sink / –15 mA source - supports direct fan-out to multiple TTL loads without buffering |
| IOFF Leakage | ±100 μA at VCC = 0 V - prevents damaging backflow current during partial power-down sequences |
| Operating Temperature | –40 °C to +85 °C - validated for industrial ambient conditions without derating |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V - guarantees reliable recognition of TTL-compatible logic levels |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for board-level handling robustness |
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 with thermal and mechanical reliability in reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input per OR gate - accepts active-HIGH logic signals with TTL-compatible thresholds |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input per OR gate - fully symmetrical with A inputs; no priority or enable function |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | OR output per gate - actively driven HIGH/LOW; disabled (high-Z) when VCC = 0 V via IOFF |
| 7 | GND | Ground reference - must be connected to system 0 V plane; serves as return path for all I/O and supply currents |
| 14 | VCC | Positive supply - powers internal BiCMOS circuitry; IOFF activation occurs when voltage drops below ~0.5 V |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS process architecture | Delivers 2.3 ns typical propagation delay at 5 V while maintaining CMOS-level input current (<±1 μA) |
| IOFF partial power-down | Automatically places outputs in high-impedance state when VCC = 0 V, eliminating backfeed risk in multi-supply systems |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II Level A - prevents destructive latch-up under transient overvoltage |
| Direct TTL interface | Accepts standard TTL output voltages (0.4 V/2.4 V) without level-shifting or pull-up resistors |
| Output skew control | ≤0.5 ns max skew between any two outputs - ensures deterministic timing alignment in parallel data paths |
Applications
| Industrial PLC I/O Expansion | Legacy Bus Interface Buffering |
|---|---|
Use Scenario: Adding discrete OR logic to merge multiple sensor fault signals into a single system alert line in programmable logic controller racks. IC Role / Device Role / Timing Role: Combinational logic gate aggregating up to four independent digital inputs into one active-HIGH alarm output. Use Value: Enables hardware-level fault prioritization without CPU intervention; IOFF prevents backfeed when PLC backplane rails are sequenced independently. |
Use Scenario: Interfacing ISA or PCI bus control lines (e.g., IOR#, IOW#) between legacy microcontrollers and modern peripheral ASICs. IC Role / Device Role / Timing Role: Signal-level OR gate reconstructing shared bus strobes from multiple address-decoded sources. Use Value: Sub-4 ns propagation ensures timing compliance with 8 MHz ISA bus setup/hold windows; TTL compatibility eliminates external level translation. |
| FPGA Companion Logic | Power-Aware System Control |
Use Scenario: Providing glue logic between FPGA I/O banks and external peripherals requiring OR-combined enable or reset signals. IC Role / Device Role / Timing Role: Off-FPGA combinational element synchronizing asynchronous reset assertions across multiple subsystems. Use Value: BiCMOS speed matches FPGA I/O toggle rates; TSSOP14 footprint allows placement adjacent to BGA packages without routing congestion. |
Use Scenario: Managing power sequencing in multi-rail embedded systems where subsystems power down independently but share status lines. IC Role / Device Role / Timing Role: OR gate merging "power good" signals from isolated DC/DC converters feeding different voltage domains. Use Value: IOFF ensures no current flows from live rails into powered-down sections - critical for meeting IEC 62368-1 safety isolation requirements. |
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 wider body (5.3 mm) and 0.635 mm pitch | Less suitable for ultra-dense layouts; higher thermal resistance than TSSOP | Select only if SSOP footprint already standardized in legacy design |
| 74LVC32APW | 3.3 V only (1.65–3.6 V); lower drive (24 mA), no IOFF; LVC logic family | Not compatible with 5 V TTL systems; lacks power-down protection | Use only in pure 3.3 V domains where IOFF is unnecessary and speed margin permits |
Compared with SN74ABT32DBR and 74LVC32APW, the 74ABT32PW uniquely balances 5 V TTL interoperability, sub-4 ns speed, and IOFF-enabled safe partial shutdown - making it the sole choice for industrial control systems requiring both legacy compatibility and modern power management.

FAQ
Can 74ABT32PW operate at 3.3 V?
No. The 74ABT32PW is specified only for 4.5 V to 5.5 V supply operation. At 3.3 V, input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) remain valid, but output drive strength, propagation delay, and IOFF functionality are not guaranteed. Use 74LVC32 for 3.3 V systems.
Does IOFF protect against reverse current when only one supply rail is active?
Yes. IOFF activates whenever VCC drops below ~0.5 V, forcing all outputs into high-impedance regardless of input states or other system rails. This prevents backflow from live 5 V signals into a powered-down section - confirmed by ±100 μA max IOFF leakage at VCC = 0 V.
What is the maximum capacitive load this device can drive reliably?
The 74ABT32PW is characterized with 50 pF load in dynamic testing (Table 8). While not explicitly rated for higher capacitance, its 20 mA sink capability supports ≤100 pF loads at full speed if trace lengths are short and rise/fall times remain within 10 ns/V input transition limit.
Is the TSSOP14 package RoHS compliant and lead-free?
Yes. The 74ABT32PW in SOT402-1 package meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound, as documented in Nexperia's official compliance statements and material declarations.
