Revised November 1999 74AC175 * 74ACT175 Quad D-Type Flip-Flop General Description Features The AC/ACT175 is a high-speed quad D-type flip-flop. The device is useful for general flip-flop requirements where clock and clear inputs are common. The information on the D-type inputs is stored during the LOW-to-HIGH clock transition. Both true and complemented outputs of each flipflop are provided. A Master Reset input resets all flip-flops, independent of the Clock or D-type inputs, when LOW. ICC reduced by 50% Edge-triggered D-type inputs Buffered positive edge-triggered clock Asynchronous common reset True and complement output Outputs source/sink 24 mA ACT175 has TTL-compatible inputs Ordering Code: Order Number 74AC175SC 74AC175SJ 74AC175MTC Package Number Package Description M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow Body M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MTC16 74AC175PC N16E 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide 74ACT175SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow Body 74ACT175SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74ACT175MTC MTC16 74ACT175PC N16E 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Device also available in Tape and Reel.

The Clock and Master Reset are common. The four flip-flops will store the state of their individual D inputs on the LOWto-HIGH clock (CP) transition, causing individual Q and Q outputs to follow. A LOW input on the Master Reset (MR) will force all Q outputs LOW and Q outputs HIGH independent of Clock or Data inputs. The AC/ACT175 is useful for general logic applications where a common Master Reset and Clock are acceptable.
