This 8 bit D-TYPE FLIP FLOP is controlled by a clock input (CK) and an output enable input (OE). On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs. While the OE input is at low level, the eight outputs will be in a normal logic state (high or low logic level) and while OE is at high level the outputs will be in a high impedance state. The output control does not affect the internal operation of flip-flops; that is, the old data can be retained or the new data can be entered even while the outputs are off. The M74HCT374 is designed to directly interface HSC2MOS systems with TTL and NMOS components. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

(Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/8 (per Flip Flop) and the CPD when n pcs of Flip Flop operate, can be gained by the following equation: CPD(TOTAL) = 30 + 18 x n (pF) TEST CIRCUIT TEST tPLH, tPHL tPZL, tPLZ tPZH, tPHZ CL = 50pF/150pF or equivalent (includes jig and probe capacitance) R1 = 1KΩ or equivalent RT = ZOUT of pulse generator (typically 50Ω) SWITCH Open VCC GND 5/11 M74HCT374 WAVEFORM 1: CK TO Qn PROPAGATION DELAYS, MAXIMUM CK FREQUENCY, Dn TO CK SETUP AND HOLD TIMES (f=1MHz; 50% duty cycle) 6/11 M74HCT374 WAVEFORM 2: OUTPUT ENABLE AND DISABLE TIMES (f=1MHz; 50% duty cycle) W AVEFORM 3: MINIMUM PULSE WIDTH (CK) (f=1MHz; 50% duty cycle) 7/11 M74HCT374 Plastic DIP-20 (0.25) MECHANICAL DATA mm.
