Hex D-type flip-flop with reset; positive edge-trigger
The 74LV174 is a low–voltage Si–gate CMOS device and is pin and function compatible with the 74HC/HCT174. The 74LV174 has six edge–triggered D–type flip–flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs load and reset (clear) all flip–flops simultaneously. The register is fully edge–triggered. The state of each D input, one set– up time prior to the LOW–to–HIGH clock transition, is transferred to the corresponding output of the flip–flop. A LOW level on the MR input forces all outputs LOW, independently of clock or data inputs. The device is useful for applications requiring true outputs only and clock and master reset inputs that are common to all storage elements. Output voltage levels are compatible with input levels of CMOS, NMOS and TTL ICS Supply voltage range: 1.2 to 5.5 V Low input current: 1.0 ; 0.1 at = 25 ° Output current: 6 mA at Vcc = 3.0 V; 12 mA at Vcc = 4.5 V High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION IN74LV174N Plastic IN74LV174D SOIC IZ74LV174 Chip TA = -40° to 125° C for all packages
