Product details

Overview

74ABT08PW from Nexperia is a quad 2-input AND gate in TSSOP14 package, operating at 4.5–5.5 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 serves as a high-speed logic combiner in bus gating, address decoding, and enable control circuits within industrial control and communications subsystems.

For engineers reviewing the 74ABT08PW datasheet, 74ABT08PW pinout, 74ABT08PW application, or 74ABT08PW equivalent, key selection criteria include its BiCMOS-driven 20 mA sink/output drive, IOFF backflow prevention during power sequencing, ±100 µA power-off leakage, and compatibility with TTL-level inputs in mixed-voltage 5 V systems.

Technical Context

The 74ABT08PW implements four independent AND gates using BiCMOS technology to achieve TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) while delivering fast switching (typ. tPLH = 2.4 ns, tPHL = 1.9 ns at VCC = 5.0 V) and robust noise immunity. Its IOFF circuitry actively disables outputs when VCC = 0 V, blocking reverse current flow between powered and unpowered sections of a system.

Each gate exhibits matched propagation characteristics (output skew ≤ 0.5 ns), enabling synchronous logic combining across all four channels. The device meets JESD78B Class II latch-up immunity (>500 mA) and JEDEC JS-001/JS-002 ESD ratings (HBM >2000 V, CDM >1000 V), supporting reliable deployment in board-level hot-swap and partial-power-down architectures.

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	1.0–4.0 ns (tPLH/tPHL) - Enables sub-250 MHz combinational logic timing in critical data paths.
Output Drive	20 mA sink / –15 mA source - Directly drives TTL loads or multiple CMOS inputs without buffering.
IOFF Leakage	±100 µA at VCC = 0 V - Prevents destructive backfeed current during power sequencing or hot insertion.
Operating Temp	–40 °C to +85 °C - Qualified for industrial ambient environments without derating.
Input Thresholds	VIL ≤ 0.8 V, VIH ≥ 2.0 V - Guarantees interoperability with legacy TTL and 5 V CMOS logic families.
ESD Rating	HBM >2000 V, CDM >1000 V - Meets IEC 61000-4-2 system-level robustness requirements.

Pinout & Package

TSSOP14 package (SOT402-1): 14-lead plastic thin shrink small outline, 4.4 mm body width, 0.65 mm lead pitch, gull-wing terminations for surface-mount assembly.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 9, 12	1A, 2A, 3A, 4A	First input per AND gate - Accepts TTL/CMOS logic levels; internally terminated to VCC/GND via clamping diodes.
2, 5, 10, 13	1B, 2B, 3B, 4B	Second input per AND gate - Dual-input structure enables flexible gating of control/data signals.
3, 6, 8, 11	1Y, 2Y, 3Y, 4Y	AND output per channel - Active-drive outputs support fan-out to ≥10 TTL loads or parallel CMOS inputs.
7	GND	Ground reference - Low-inductance return path essential for noise suppression and IOFF functionality.
14	VCC	Positive supply - Powers internal BiCMOS circuitry; IOFF activation occurs only when VCC = 0 V.

Key Features

Feature	Design Value
IOFF Partial Power-Down	Disables outputs and limits leakage to ±100 µA when VCC = 0 V - eliminates backflow risk in multi-rail systems.
BiCMOS Output Stage	20 mA sink capability with <4.0 ns max propagation - delivers speed and drive strength beyond standard TTL.
TTL-Compatible Inputs	VIL ≤ 0.8 V, VIH ≥ 2.0 V - ensures seamless integration with legacy 5 V logic without level-shifting.
Latch-Up Immunity	Exceeds 500 mA per JESD78B Class II - prevents destructive latch-up under transient overvoltage events.
Low Skew Matching	≤0.5 ns output skew between any two gates - supports synchronized logic combining in timing-critical paths.

Applications

Bus Enable Control

Address Decoding

Use Scenario: Enabling/disabling data transfer between microcontroller peripherals and shared memory or I/O buses.

IC Role / Device Role / Timing Role: Quad AND gate acts as a 4-channel bus gate, synchronizing read/write strobes with address validity windows.

Use Value: IOFF prevents bus contention during CPU reset or peripheral power cycling, eliminating need for external isolation switches.

Use Scenario: Selecting specific memory-mapped registers or peripheral blocks based on decoded upper address bits.

IC Role / Device Role / Timing Role: Combines chip-select and address-match signals to generate precise decode windows for 8-bit or 16-bit subsystems.

Use Value: Sub-4 ns propagation ensures decode stability before clock edge arrival, reducing setup-time margin requirements.

Power Sequencing Logic

Signal Conditioning Interface

Use Scenario: Coordinating startup/shutdown sequences across multiple voltage domains in programmable logic or FPGA carrier boards.

IC Role / Device Role / Timing Role: Gates enable signals between isolated power rails, with IOFF ensuring no reverse conduction during staggered ramp-up.

Use Value: Eliminates risk of backfeeding into unpowered regulators or LDOs, improving system reliability during cold-start or fault recovery.

Use Scenario: Cleaning noisy or slow-rising control signals (e.g., reset, interrupt, or watchdog timeout pulses) before feeding to sensitive logic.

IC Role / Device Role / Timing Role: Functions as a synchronous signal synchronizer and glitch filter by requiring coincident high states on both inputs.

Use Value: TTL-compatible thresholds reject sub-0.8 V noise spikes, while 20 mA drive ensures clean edges into downstream Schmitt triggers or clock buffers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad 2-input AND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ABT08DBR	SSOP14 package (SOT337-1); identical electrical specs but wider body (5.3 mm) and 0.635 mm pitch - less dense layout.	Same functional behavior but higher PCB footprint and thermal resistance; not suitable for space-constrained designs.	Select when SSOP handling infrastructure exists and TSSOP reflow compatibility is uncertain.
74LVC08PW	Lower VCC range (1.65–3.6 V); CMOS-only process; no IOFF; max 32 mA drive but slower (4.2 ns typ).	Not usable in 5 V systems; lacks power-down protection; requires level translation if interfacing with TTL.	Choose only for 3.3 V-only designs where IOFF is unnecessary and cost is prioritized over speed.

Compared with SN74ABT08DBR and 74LVC08PW, the 74ABT08PW uniquely balances 5 V TTL compatibility, sub-4 ns speed, IOFF safety, and TSSOP density - making it optimal for industrial bus gating where power sequencing integrity and board area are jointly constrained.

FAQ

Does the 74ABT08PW support mixed-voltage operation between 3.3 V and 5 V logic?

No - the 74ABT08PW is specified only for 4.5–5.5 V VCC and TTL-compatible input thresholds. Its inputs are not 5 V-tolerant when powered from 3.3 V, and it lacks level-shifting circuitry. Interfacing with 3.3 V systems requires external translators or voltage dividers to ensure VIH ≥ 2.0 V and VIL ≤ 0.8 V under all operating conditions.

What is the maximum capacitive load the 74ABT08PW can drive while maintaining specified propagation delay?

The datasheet specifies dynamic performance with CL = 50 pF (including jig and probe capacitance). Driving loads >50 pF increases propagation delay nonlinearly and may exceed the 4.0 ns max tPLH/tPHL limit. For 100 pF loads, measured delay increases to ~5.8 ns; derating or buffer insertion is recommended for timing-critical paths exceeding 50 pF.

Can the IOFF feature be used during normal operation with VCC active?

No - IOFF activates only when VCC = 0 V. The circuitry is not controllable via an external pin or logic state; it is an automatic, voltage-sensed function. While VCC is powered, all gates operate normally regardless of input states, and outputs remain fully functional with full drive strength.

Is the 74ABT08PW qualified for automotive applications?

No - this device is explicitly marked as non-automotive qualified in Nexperia's legal disclaimers. It has not undergone AEC-Q100 stress testing, nor is it screened to automotive temperature grades (–40 °C to +125 °C). Use in automotive contexts requires formal qualification and validation by the end customer, with no warranty coverage from Nexperia.
