Nexperia USA Inc. 74HCT08PW,118

Overview

74HCT08PW,118 from Nexperia is a quad 2-input AND gate IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), 4.5–5.5 V supply range, and TSSOP14 package (SOT402-1). It delivers 14 ns typical propagation delay at 4.5 V, supports -40 °C to +125 °C operation, and integrates input clamp diodes for overvoltage-tolerant interfacing in digital logic control subsystems.

For engineers reviewing the 74HCT08PW,118 datasheet, 74HCT08PW,118 pinout, 74HCT08PW,118 application, or 74HCT08PW,118 equivalent, key selection criteria include TTL-level input compatibility, guaranteed 125 °C operation, TSSOP14 thermal performance (7.3 mW/K derating above 81 °C), and compliance with JEDEC JESD7A and JESD8C standards.

Technical Context

This device implements four independent AND logic functions in a single monolithic CMOS structure, with inputs designed for direct interface to legacy TTL outputs without level-shifting. Each gate features symmetric input clamping diodes enabling current-limited connection to signals exceeding VCC.

Its static output drive capability is specified at ±4.0 mA (VOH ≥ 3.98 V, VOL ≤ 0.26 V at VCC = 4.5 V), and dynamic behavior is characterized under 50 pF load with defined transition rate constraints (6 ns rise/fall time at 3.0 V input swing).

Equivalent & Alternatives

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

Compared with 74HCT08PW,118, the SO14 variant offers easier manual assembly and higher thermal mass, while the TI SN74HCT08DR provides identical logic behavior with minor supply current trade-offs - both require verification of layout-specific thermal management and PCB stack-up compatibility.

FAQ

Can 74HCT08PW,118 operate reliably at 3.3 V supply?

No. The 74HCT08PW,118 is specified only for 4.5 V to 5.5 V operation per its recommended conditions table. At 3.3 V, input thresholds (VIH = 2.0 V min) become non-compliant, and output drive strength degrades beyond specification - use 74HC08PW for 2.0–6.0 V wide-range operation instead.

Is the exposed thermal pad on the TSSOP14 package electrically connected?

No. The exposed pad in SOT402-1 is a mechanical thermal enhancement feature only. Nexperia documentation explicitly states it has no electrical function and may remain floating or be connected to GND if soldered - no internal bond wire or silicon connection exists.

What is the maximum clock frequency supported for toggle operation?

While not a clocked device, the 74HCT08PW,118 supports reliable data toggling up to ~35 MHz based on worst-case propagation delay (36 ns at -40 °C to +125 °C) and transition time (22 ns), assuming 50 pF load and proper decoupling - actual limit depends on system-level signal integrity.

Does this part support hot-swap or live-insertion?

No. The 74HCT08PW,118 lacks hot-swap protection circuitry such as power-on reset, bus-hold, or Ioff. Applying VCC before GND or powering inputs before VCC risks latch-up per JESD78 Class II Level B testing - always follow proper power sequencing (GND first, then VCC, then inputs).
