Key Features
- 6 open-drain inverting buffers with 24 mA sink current enable direct drive of LEDs, relays, and bus pull-up circuits
- ACT family logic operates from 4.5 V to 5.5 V supply with TTL-compatible input thresholds for mixed 3.3 V/5 V systems
- 14-pin DIP package with RoHS-compliant finish supports through-hole prototyping and legacy board manufacturing
Applications
The CD74ACT05E is used in level translation, bus buffering, and open-drain wired-OR logic configurations in microcontroller and FPGA interface circuits where multiple drivers must share a common signal line with a pull-up resistor. Its 24 mA output sink current makes it suitable for direct LED indicator drive and relay coil control without external transistor stages. The ACT family TTL-compatible input thresholds allow the device to interface between 3.3 V logic output signals and 5 V bus systems in mixed-voltage digital designs.

Frequently Asked Questions
How many inverting buffer channels does the CD74ACT05E provide, and what is the output sink current?
The CD74ACT05E contains 6 independent open-drain inverting buffer channels, each capable of sinking up to 24 mA, which allows direct drive of standard LEDs, small relays, and other low-current loads without additional driver transistors.
What supply voltage does the CD74ACT05E require, and does it accept 3.3 V logic inputs?
The CD74ACT05E operates from a supply voltage of 4.5 V to 5.5 V and uses ACT family TTL-compatible input thresholds, typically accepting logic high at 2 V, which means it can reliably interpret 3.3 V CMOS logic outputs even when powered from a 5 V rail.
In what wired-OR bus configurations is the CD74ACT05E's open-drain output most useful?
The open-drain outputs of the CD74ACT05E allow multiple device outputs to be tied together with a single pull-up resistor on a shared bus, creating a wired-OR logic topology commonly used in I2C-like communication lines and interrupt aggregation circuits where multiple sources must signal on a single wire.
How does the CD74ACT05E's load capacitance rating affect signal timing in high-speed logic designs?
The CD74ACT05E is characterized with a 50 pF load capacitance, meaning propagation delay specifications are valid up to 50 pF per output. Driving loads above 50 pF will increase propagation delay beyond the datasheet typical values, which must be accounted for in timing closure analysis of high-speed logic boards.
