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.
This document is a product specification datasheet for the Philips 74F245, an octal transceiver with non-inverting 3-State bus compatible outputs. The device features bidirectional data transfer capabilities with separate transmit and receive directions, allowing for easy cascading via an Output Enable input.
| Operating Temperature | 0 to +70 °C |
|---|---|
| Propagation Delay | 25 ns (Typical) |
| Output Source Current | 15 mA |
The OE input is an Output Enable input used for easy cascading of the device.
The TR input controls the direction of data transfer between the two buses.
The outputs are placed in a high impedance state to prevent bus loading.
