INTEGRATED CIRCUITS 74F2245 Octal transceiver with 30W equivalent output termination (3-State) Product specification IC15 Data Handbook 1996 May 10 Philips Semiconductors Philips Semiconductors Product specification Octal transceiver with 30W equivalent output termination (3-State) 74F2245 FEATURES • Octal bidirectional bus interface • 30 Ohm output termination for driving DRAM • Outputs are placed in high impedance state during power-off conditions PIN CONFIGURATION T/R 1 A0 A1 A2 A3 A4 2 3 4 5 6 7 8 9 20 VCC 19 OE 18 B0 17 B1 16 B2 15 B3 14 B4 13 B5 12 B6 11 B7 • SSOP Type II package DESCRIPTION The 74F2245 is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both transmit and receive directions.
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.
The 30 Ohm series termination on the outputs reduces over/undershoot making them ideal for driving DRAM.
