Manufacturer: National

Overview: MM54C74 MM74C74 Dual D Flip-Flop February 1988 MM54C74 MM74C74 Dual D.

General Description

The MM54C74 MM74C74 dual D flip-flop is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors Each flipflop has independent data preset clear and clock inputs and Q and Q outputs The logic level present at the data input is transferred to the output during the positive going transition of the clock pulse Preset or clear is independent of the clock and accomplished by a low level at the preset or clear input Y Y Low power Medium speed operation 50 nW (typ ) 10 MHz (typ ) with 10V supply Applications Y Y Y Y Y

Key Features
