It achieves high speed operation similar to equiv- alent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHCT245A is intended for bidirectional asynchronous communication between data busses. The direction of data transmission is deter- mined by the level of the T/R input. The enable input can be used to disable the device so that the busses are effectively isolated. Protection circuits ensure that 0V to 7V can be applied to the input and output(1) pins without regard to the supply voltage. These circuits prevent device destruction due to mismatched supply and input/output voltages. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. Note: 1. Outputs in OFF-State Ordering Information Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering number. Pb-Free package per JEDED J-STD-020B.
