概述

Description

SN74HCT04D is a hex inverter in the 74HCT family. It contains six independent NOT gates in a single 14‑pin package (DIP). Key points:
- Function: Inverts six discrete input signals (logic high → low, low → high).
- Technology: High-speed CMOS with TTL‑compatible inputs.
- Supply: Typically 4.5–5.5 V; low static power consumption.
- Package/pinout: DIP‑14. GND on pin 7, Vcc on pin 14. Gate pairs (A→Y) are: 1A/1Y (pins 1–2), 2A/2Y (3–4), 3A/3Y (5–6), 4A/4Y (9–8), 5A/5Y (11–10), 6A/6Y (13–12).
Common uses: signal inversion, buffering/increasing drive, level shifting between TTL and CMOS, simple RC oscillators, or clock/phase generation with proper design.

Features

Here are the typical features of the SN74HCT04D:
- Hex inverter: six independent inverters
- HCT logic: TTL-compatible input thresholds
- Single-supply operation: 4.5 V to 5.5 V
- CMOS outputs: standard logic-level signaling, suitable for CMOS/TTL loads
- Low static/dynamic power consumption
- Fast switching with high noise margins
- 14-pin package (D suffix indicates the SOIC/SMT variant; also available in other packages)
- ESD protection on inputs
- Wide operating temperature range (typical industrial/extended ranges; check datasheet for exact values)
Use: general-purpose signal inversion, buffering, and level shifting between TTL and CMOS systems.

Package

14-pin small-outline package (SOIC). The “D” suffix denotes the SOIC package for SN74HCT04D.

Pinout

- Pin count: 14-pin DIP
- Function: Hex inverter (six independent inverters). Inputs: A1(at pin1), A2(pin3), A3(pin5), A4(pin9), A5(pin11), A6(pin13). Outputs: Y1(pin2), Y2(pin4), Y3(pin6), Y4(pin8), Y5(pin10), Y6(pin12). Vcc on pin14; GND on pin7.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational corporation that designs and manufactures semiconductors, integrated circuits, sensors, and related electronic components and software.

Application
