描述 Description

DESCRIPTION
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
• The -1 version sinks 48mA
