74VHCT08A Quad 2-Input AND Gate
July 1997 Revised February 2005
74VHCT08A Quad 2-Input AND Gate
General Description
The VHCT08A is an advanced high speed CMOS 2 Input AND Gate fabricated with silicon gate CMOS technology. It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The internal circuit is composed of 4 stages including buffer output, which provide high noise immunity and stable output. Protection circuits ensure that 0V to 7V can be applied to the input pins without regard to the supply voltage and to the output pins with VCC 0V. These circuits prevent device destruction due to mismatched supply and input/ output voltages. This device can be used to interface 3V to 5V systems and two supply systems such as battery backup.

Note 2: Absolute Maximum Ratings are values beyond which the device may be damaged or have its useful life impaired. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside databook specifications. Note 3: HIGH or LOW state. IOUT absolute maximum rating must be observed. Note 4: VCC 0V. Note 5: VOUT GND, V OUT ! VCC (Outputs Active). Note 6: Unused inputs must be held HIGH or LOW. They may not float.
