Product Overview
The CD74HC245E is a high-speed octal 3-state bidirectional Transceiver intended for 2-way asynchronous communication between data buses. It has high drive current outputs which enable high-speed operation while driving large bus capacitances. It provides the low power consumption of standard CMOS circuits with speeds and drive capabilities comparable to that of LSTTL circuits. The CD74HC245 allows data transmission of the B bus or from the B bus to the A bus. The logic level at the direction input (DIR) determines the direction. The output enable input (OE\), when high, puts the I/O ports in the high-impedance state. The HC245 is similar in operation to the HC640 and the HC643.
- Buffered inputs
- Bus line driving capability
- Balanced propagation delay and transition times
- Significant power reduction compared to LSTTL logic ICs
- High noise immunity - NIL = 30%, NIH = 30% of VCC at VCC = 5V
- Typical propagation delay (A to B, B to A) 9ns at VCC = 5V, CL = 15pF, TA = 25°C
- Standard outputs - 10 LSTTL loads
- Bus driver outputs - 15 LSTTL loads
Applications
Industrial, Automation & Process Control, Signal Processing, Communications & Networking
