KK74LV174

TECHNICAL DATA KK74LV174 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 µА; 0.1 µА at Т = 25 °С • 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 KK74LV174N Plastic KK74LV174D SOIC TA = -40° to 125° C for all packages PIN ASSIGNMENT MR Q0 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 V CC Q5 D5 D4 Q4 D3 Q3 CP LOGIC DIAGRAM D0 D1 Q1 D2 Q2 GND FUNCTION TABLE CP Inputs MR CP X Dn X H L L X X Outputs Qn L H L no change no change MR L H PIN 16=VCC PIN 08 = GND H H H H= high level L = low level X = don’t care 1 KK74LV174 MAXIMUM RATINGS* Symbol VCC IIK * IO * ICC IGND PD 1 2 Parameter DC supply voltage Input diode current Output diode current Output source or sink current VCC current GND current Power dissipation per package: * Plastic DIP SO Storage Temperature Lead Temperature, 1.5 mm (Plastic DIP Package), 0.3 mm (SO Package) from Case for 4 Seconds 4 Value -0.5 to +5.0 ±20 ±50 ±25 ±50 ±50 750 500 -65 to +150 260 Unit V mA mA mA mA mA mW IOK * 3 Tstg TL * °C °C Maximum Ratings are those values beyond which damage to the device may occur.
