The VHCT240A is an advanced high-speed CMOS octal bus transceiver fabricated in silicon-gate CMOS technology. It achieves high-speed operation similar to the equivalent bipolar Schottky TTL while maintaining low power consumption in CMOS. The VHCT240A is an inverting 3-state buffer with two active-low output enable pins. These devices are designed for use as 3-state memory address drivers, clock drivers, and bus transmitter/receivers. The input protection circuit ensures that 0 to 7V can be applied to the input and output (Note 1) pins regardless of the supply voltage. These circuits prevent the device from being damaged due to power supply and input/output voltage mismatch. This device can be used to interface 5V to 3V systems and two power systems such as backup batteries.
