Revised February 1999 MM74HCT32 Quad 2-Input OR Gate General Description The MM74HCT32 is a logic function fabricated by using advanced silicon-gate CMOS technology, which provides the inherent benefits of CMOS—low quiescent power and wide power supply range. This device is input and output characteristic and pin-out compatible with standard 74LS logic families. All inputs are protected from static discharge damage by internal diodes to VCC and ground. MM74HCT devices are intended to interface between TTL and NMOS components and standard CMOS devices. These parts are also plug-in replacements for LS-TTL devices and can be used to reduce power consumption in existing designs. Features ■ TTL, LS pin-out and threshold compatible ■ Fast switching: tPLH , tPHL = 10 ns (typ) ■ Low power: 10 µW at DC ■ High fan-out, 10 LS-TTL loads Ordering Code: Order Number Package Number MM74HCT32M MM74HCT32SJ MM74HCT32MTC 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150” Narrow M14D 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MTC14 MM74HCT32N Package Description M14A N14A 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001 0.300” Wide Devices also available in Tape and Reel.
