Nexperia USA Inc. 74HCT08PW,112

Overview

74HCT08PW,112 from Nexperia is a quad 2-input AND gate IC operating at 4.5–5.5 V supply, with typical propagation delay of 19 ns at 5 V, CMOS input levels, and TTL-compatible output drive. It performs basic logic conjunction in digital control signal routing for industrial PLC I/O modules.

For engineers reviewing the 74HCT08PW,112 datasheet, 74HCT08PW,112 pinout, 74HCT08PW,112 application, or 74HCT08PW,112 equivalent, key selection criteria include input threshold compatibility with 5 V TTL systems, output sink/source capability under load, propagation delay consistency across temperature, and SO-14 package thermal performance in dense PCB layouts.

Technical Context

This device implements four independent AND gates in a single monolithic silicon die using high-speed CMOS (HCT) process technology. Each gate features buffered outputs, Schmitt-trigger-free inputs, and guaranteed noise immunity of ≥400 mV at V_CC = 5 V.

The logic function conforms to IEEE Std 91-1984 and IEC 60617-12, with defined static current draw ≤1 μA at 25 °C and output voltage levels meeting VOH ≥ 4.4 V (IOH = –4 mA), VOL ≤ 0.4 V (IOL = 4 mA).

FAQ

Is 74HCT08PW,112 pin-compatible with 74LS08?

Yes - it uses identical SO-14 pinout and meets all 74LS08 DC and AC specifications including input thresholds, output drive, and propagation delay. No board redesign or schematic change is required for substitution in existing 5 V TTL systems.

Can 74HCT08PW,112 operate at 3.3 V supply?

No - its absolute maximum rating specifies V_CC = 5.5 V, and minimum operating voltage is 4.5 V. At 3.3 V, input thresholds are not guaranteed, and output drive falls outside specification; use 74LVC08AD instead for 3.3 V operation.

What is the maximum capacitive load this device can drive reliably?

It is characterized up to 50 pF load capacitance with specified timing and voltage margins. Driving >50 pF may increase propagation delay beyond 19 ns and reduce noise margin; add a buffer stage for loads exceeding 75 pF or trace lengths over 10 cm.

Does 74HCT08PW,112 support hot-swap or live-insertion?

No - it lacks bus-hold, power-up 3-state, or I_OFF protection. Applying V_CC while inputs are driven can cause excessive current flow; always power up V_CC before applying input signals in hot-swap scenarios.
