MC54/74F534 OCTAL D-TYPE FLIP-FLOP WITH 3-STATE OUTPUTS The MC54 / 74F534 is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus oriented applications. A buffered Clock (CP) and Output Enable (OE) are common to all flip-flops. The F534 is the same as the F374 except that the outputs are inverted.

FUNCTIONAL DESCRIPTION LOW-to-HIGH Clock (CP) transition. With the Output Enable (OE) LOW, the contents of the eight flip-flops are available at the outputs. When the OE is HIGH, the outputs go to the high impedance state. Operation of the OE input does not affect the state of the flip-flops. The F534 consists of eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will store the state of their individual D inputs that meet the setup and hold times requirements on the DC CHARACTERISTICS OVER OPERATING TEMPERATURE RANGE (unless otherwise specified) Limits Symbol Min Parameter VIH Input HIGH Voltage VIL Input LOW Voltage VIK Input Clamp Diode Voltage VOH Output HIGH Voltage VOL Output LOW Voltage IOZH Typ Max 2.0 54, 74 2.4 74 2.7 Unit Test Conditions V Guaranteed Input HIGH Voltage 0.8 V Guaranteed Input LOW Voltage – 1.2 V IIN = – 18 mA VCC = MIN V IOH = – 3.0 mA VCC = 4.5 V 3.3 3.3 V IOH = – 3.0 mA VCC = 4.75 V 0.5 V IOL = 24 mA VCC = MIN Output OFF Current — HIGH 50 µA VOUT = 2.7 V VCC = MAX IOZL Output OFF Current — LOW – 50 µA VOUT = 0.5 V VCC = MAX IIH Input HIGH Current IIL Input LOW Current IOS Output Short Circuit Current (Note 2) ICCZ Power Supply Current 0.35 20 100 – 60 55 µA VIN = 7.0 V VCC = MAX – 0.6 mA VIN = 0.5 V VCC = MAX –150 mA VOUT = 0 V VCC = MAX 86 mA Dn = Gnd OE = 4.5 V VCC = MAX NOTES: 1.
