Revised February 2005 74VHCT08A Quad 2-Input AND Gate General Description Features 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. ■ High speed: tPD 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. ■ Low noise: VOLP 5.0 ns (typ) at TA ■ High noise immunity: VIH 2.0V, VIL 25qC 0.8V ■ Power down protection is provided on all inputs and outputs 0.8V (max) ■ Low power dissipation: ICC 2 PA (max) @ TA 25qC ■ Pin and function compatible with 74HCT08 Ordering Code: Order Number Package Package Description Number 74VHCT08AM M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 74VHCT08AMX_NL (Note 1) M14A Pb-Free 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 74VHCT08ASJ M14D Pb-Free 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74VHCT08AMTC MTC14 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74VHCT08AMTCX_NL (Note 1) MTC14 Pb-Free 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74VHCT08AN N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Surface mount packages are also available on Tape and Reel.
