Product Overview
Designed for asynchronous, bidirectional communication between data buses, this DV74ALS245AN octal transceiver uses Advanced Low-Power Schottky (ALS) logic. Operating on a standard 5V supply, it provides two-way data paths governed by directional control lines and 3-state outputs that isolate system buses when disabled.
Key Features
- 8-bit bidirectional data transmission between A and B buses
- 3-state outputs for bus-oriented system architectures
- Advanced Low-Power Schottky (ALS) TTL logic family
- 4.5V to 5.5V operating supply voltage range
- Standard 20-pin plastic dual in-line package (PDIP-20)
- Through-hole mounting with 0.300-inch (7.62 mm) row spacing
Applications
- Interfacing microprocessors with peripheral cards or memory modules
- Restoring vintage computing systems, synthesizer boards, or arcade hardware
- Breadboard prototyping and DIY 8-bit retro computing projects
Frequently Asked Questions
What logic family does this transceiver belong to?
This chip belongs to the Advanced Low-Power Schottky (ALS) TTL logic family, operating nominally at 5V.
Is this pin-compatible with standard 74ALS245 and 74LS245 transceivers?
Yes, it uses the industry-standard 20-pin DIP layout matching standard 74ALS245 and 74LS245 octal transceivers.
The '245 has kept data buses from colliding since the early days of personal computing. Pop one into the socket, set your direction pin, and let the bytes flow.
