They have the same high speed performance of LSTTL combined with true CMOS low power comsuption. These8-bit D-type flip-flops are controlled by a clock input (CK) and an ouput 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 (HC374) or their complements (HC534). While the OE input is low, the eight outputs will be in a normal logic state (high or low logic level), and while 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 application engineer has a choice of combination of inverting and non-inverting outputs. The HC374 and HC574 are identical, apart from pin layout. The 3-state output configuration and the wide choice of outline make bus-organized systems simple. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/8 (per FLIP-FLOP) and CPD when N pcs of FLIP-FLOP operate, can be gained by following equation: CPD (TOTAL) = 30 + 17 x N (pF) 6/13 M54/M74HC374/534 SWITCHING CHARACTERISTICS TEST WAVEFORM tPLH, tPHL, ts, th, tw fMAX tPLZ, tPZL The 1KΩ load resistors should be connected between outputs and VCC line and the 50pF load capacitors should be connected between outputsand GND line.
