Description and Introduction

OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS (NON INVERTED) The 74AC245B is a high-speed CMOS octal bus transceiver manufactured by STMicroelectronics. It features 3-state outputs and is designed for asynchronous communication between data buses. The device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction control (DIR) input. The output enable (OE) input can disable the device, effectively isolating the buses.

Key specifications:
- Supply Voltage Range: 2.0V to 6.0V
- High-Speed Operation: tPD = 5.5ns (Typ) at VCC = 5V
- Low Power Dissipation: ICC = 4µA (Max) at TA = 25°C
- High Noise Immunity: VNIH = VNIL = 28% VCC (Min)
- Output Drive Capability: 24mA at VCC = 5V
- Operating Temperature Range: -40°C to +85°C
- Package: 20-pin SO, TSSOP, and DIP

The 74AC245B is compatible with TTL levels and is suitable for applications requiring high-speed data transfer and bus isolation.
