Octal transceiver with direction pin (3-State)
Product specification
74ABT245
FEATURES
• Octal bidirectional bus interface
• 3-State buffers
• Output capability: +64mA/–32mA
• Latch-up protection exceeds 500mA per Jedec Std 17
• ESD protection exceeds 2000 V per MIL STD 833 Method 3015
and 200 V per Machine Model
• Power-up 3-State
• Live insertion/extraction permitted
• Inputs are disabled during 3-State mode
DESCRIPTION
The 74ABT245 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT245 device is an octal transceiver featuring non-inverting
3-State bus compatible outputs in both send and receive directions.
The control function implementation minimizes external timing
requirements. The device features an Output Enable (OE) input for
easy cascading and a Direction (DIR) input for direction control.
