Product Summary

The tc74vhc245ft is an advanced high speed CMOS OCTAL BUS TRANSCEIVER fabricated with silicon gate C2MOS technology. The tc74vhc245ft achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The tc74vhc245ftis intended for two-way asynchronous communication between data busses. The direction of data transmission is determined by the level of the DIR input. The enable input (G ) can be used to disable the device so that the busses are effectively isolated.

Parametrics
