Revised February 2005 74VHC32 Quad 2-Input OR Gate General Description Features The VHC32 is an advanced high speed CMOS 2-Input OR 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: The internal circuit is composed of 4 stages including buffer output, which provide high noise immunity and stable output. An input protection circuit ensures that 0V to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. High Noise Immunity: VNIH tPD 3.8 ns (typ) at VCC 5V Low Power Dissipation: ICC 2 PA (Max) at TA 25qC VNIL 28% VCC (Min) Power down protection is provided on all inputs Low Noise: VOLP 0.8V (Max) Pin and Function Compatible with 74HC32 Ordering Code: Order Number Package Package Description Number 74VHC32M M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 74VHC32MX_NL (Note 1) M14A Pb-Free 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 74VHC32SJ M14D Pb-Free 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74VHC32MTC MTC14 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74VHC32MTCX_NL (Note 1) MTC14 Pb-Free 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74VHC32N 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.
