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

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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
