IN74ALS245
IN74ALS245 is Octal 3-State Noninverting Bus Transceiver manufactured by Integral.
TECHNICAL DATA
Octal 3-State Noninverting Bus Transceiver
This device contains eight pairs of 3-state logic elements designed for asynchronous two-way munication between data buses.
These circuits are suited for use in memory, microprocessor systems and asynchronous bi-directional data buses. The Enable input (E) can be used to isolate the buses.
- Non-inverting logic output
- Switching response specified into 500Ω/50 p F
- Switching specifications guaranteed over full temperature and VCC range
- Low level drive current:
54ALS = 12 m A, 74ALS = 24 m A
