74ALS245A-1 Octal transceiver

The 74ALS245A 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 (R/T) input for direction control. The 74ALS245A-1 is the same as the 74ALS245A except that both ports sink 48mA within the ±5% VCC range..

Features

• Octal bidirectional bus interface
• 3-State buffer outputs sink 24mA and source 15mA
• Outputs are placed in high impedance state during power-off conditions PIN CONFIGURATION T/R 1 A0 A1 A2 A3 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
