MM74HC273 Octal D-Type Flip-Flops with Clear September 1983 Revised February 1999 MM74HC273 Octal D-Type Flip-Flops with Clear General Description The MM74HC273 edge triggered flip-flops utilize advanced silicon-gate CMOS technology to implement D-type flipflops. They possess high noise immunity, low power, and speeds comparable to low power Schottky TTL circuits. This device contains 8 master-slave flip-flops with a common clock and common clear. Data on the D input having the specified setup and hold times is transferred to the Q output on the LOW-to-HIGH transition of the CLOCK input. The CLEAR input when LOW, sets all outputs to a low state. Each output can drive 10 low power Schottky TTL equivalent loads. The MM74HC273 is functionally as well as pin compatible to the 74LS273. All inputs are protected from damage due to static discharge by diodes to VCC and ground. Features s Typical propagation delay: 18 ns s Wide operating voltage range s Low input current: 1 A maximum s Low quiescent current: 80 A (74 Series) s Output drive: 10 LS-TTL loads Ordering Code: Order Number MM74HC273M MM74HC273SJ MM74HC273MTC MM74HC273N Package Number M20B M20D MTC20 N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-153, 0.300” Wide 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Devices also ava……
