74F245
Datasheet
General description
The 74F245 is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both transmit and receive directions. The B port outputs are capable of sinking 64mA and sourcing 15mA, producing very good capacitive drive characteristics. The device features an Output Enable (OE) input for easy cascading and Transmit/Receive (T/R) input for direction control. The 3-State outputs, B0?B7, have been designed to prevent output bus loading if the power is removed from the device.
Features
- Octal bidirectional bus interface
- 3-State buffer outputs sink 64mA
- 15mA source current
- Outputs are placed in high impedance state during power-off conditions
