The Six edge-triggered D-type flip-flops common clock (CP) and master reset (MR) inputs load and Asynchronous master reset reset (clear) all flip-flops simultaneously. Output capability: standard The register is fully edge-triggered. The state of each D I category: MSI input, one set-up time prior to the LOW-to-HIGH clock CC transition, is transferred to the corresponding output of the flip-flop. GENERAL DESCRIPTION A LOW level on the MR input forces all outputs LOW, The 74HC/HCT174 are high-speed Si-gate CMOS devices independently of clock or data inputs. and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC The device is useful for applications requiring true outputs standard no. 7A. only and clock and master reset inputs that are common to all storage elements.
