Nexperia USA Inc. 74HCT04DB,112

Overview

74HCT04DB,112 from Nexperia is a hex inverter IC with TTL-compatible inputs, 14-pin SSOP package (SOT337-1), operating from 4.5 V to 5.5 V supply, delivering 4.32 V VOH at -4.0 mA and 0.26 V VOL at 5.2 mA, used for logic-level inversion and signal conditioning in digital control subsystems.

For engineers reviewing the 74HCT04DB,112 datasheet, 74HCT04DB,112 pinout, 74HCT04DB,112 application, or 74HCT04DB,112 equivalent, key selection criteria include TTL input compatibility, propagation delay ≤24 ns at VCC = 4.5 V, SO14/TSSOP/SSOP package interchangeability, and operation across -40 °C to +125 °C industrial temperature range.

Technical Context

This device implements six independent CMOS inverters with buffered outputs and input clamp diodes enabling interface to voltages exceeding VCC via current-limiting resistors. It uses standard TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and delivers rail-to-rail output swing under load.

Its static drive capability supports ±4.0 mA output current per inverter at VCC = 4.5 V, while dynamic performance is characterized with CL = 50 pF and tpd = 10–24 ns depending on supply voltage and temperature. Input capacitance is fixed at 3.5 pF per pin.

FAQ

Is 74HCT04DB,112 pin-compatible with 74HC04DB?

No. While both are hex inverters in SSOP14 packages, 74HCT04DB,112 uses TTL input thresholds (VIH ≥ 2.0 V), whereas 74HC04DB requires CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V). Swapping them may cause logic misreads in marginal voltage conditions.

Can 74HCT04DB,112 drive a 50 pF capacitive load at 10 MHz?

Yes. With CPD = 24 pF and tpd ≤ 24 ns, it delivers clean edges into 50 pF loads at 10 MHz. Total dynamic power is PD ≈ 24 pF × (5 V)² × 10 MHz = 6 mW - well within its 350 mW package limit at 25 °C.

What is the maximum recommended trace length for 74HCT04DB,112 outputs?

For signal integrity below 25 MHz, keep output traces under 10 cm with 50 Ω characteristic impedance. The 3.5 pF input capacitance and 24 ns propagation delay allow stable operation on FR-4 with controlled impedance routing and local 100 nF decoupling.

Does 74HCT04DB,112 require external pull-up or pull-down resistors on unused inputs?

Yes. Unused inputs must be tied to VCC or GND via ≤10 kΩ resistors. Floating CMOS inputs cause increased ICC, unpredictable logic states, and potential latch-up due to internal parasitic transistor activation.
