74HC374; 74HCT374 Octal D-type flip-flop; positive edge-trigger; 3-state Rev. 3 — 20 February 2018 Product data sheet 1 General description The 74HC374; 74HCT374 is an octal positive-edge triggered D-type flip-flop with 3‑state outputs. The device features a clock (CP) and output enable (OE) inputs. The flip‑flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of V . CC The 74HCT374 features reduced input threshold levels to allow interfacing to TTL logic levels. 2 Features and benefits • Input levels: –For 74HC374: CMOS level –For 74HCT374: TTL level • Octal bus interface • Non-inverting 3-state outputs • 8-bit positive, edge-triggered register • Common 3-state output enable input • Independent register and 3-state buffer operation • Complies with JEDEC standard no. 7 A • ESD protection: –HBM JESD22-A114F exceeds 2000 V –MM JESD22-A115-A exceeds 200 V • Specified from -40 °C to +85 °C and -40 °C to +125 °C
