MM74HC374 3-STATE Octal D-Type Flip-Flop September 1983 Revised May 2005 MM74HC374 3-STATE Octal D-Type Flip-Flop General Description The MM74HC374 high speed Octal D-Type Flip-Flops utilize advanced silicon-gate CMOS technology. They possess the high noise immunity and low power consumption of standard CMOS integrated circuits, as well as the ability to drive 15 LS-TTL loads. Due to the large output drive capability and the 3-STATE feature, these devices are ideally suited for interfacing with bus lines in a bus organized system. These devices are positive edge triggered flip-flops. Data at the D inputs, meeting the setup and hold time requirements, are transferred to the Q outputs on positive going transitions of the CLOCK (CK) input. When a high logic level is applied to the OUTPUT CONTROL (OC) input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements. The 74HC logic family is speed, function, and pinout compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.

Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used. www.fairchildsemi.com 2 MM74HC374 AC Electrical Characteristics VCC 5V, TA 25qC, tr t f 6 ns Parameter Conditions Typ 50 CL RL CL RL CL 45 pF k: 45 pF k: 5 pF 20 5 9 16 ns ns ns 19 17 28 25 ns ns 20 Guaranteed Limit 35 32 Units MHz ns Symbol fMAX tPHL, tPLH tPZH, tPZL tPHZ, tPLZ tS tH tW Maximum Operating Frequency Maximum Propagation Delay Clock to Q Maximum Output Enable Time Maximum Output Disable Time Minimum Setup Time Minimum Hold Time Minimum Pulse Width 3 www.fairchildsemi.com MM74HC374 AC Electrical Characteristics VCC 2.06.0V, CL 50 pF, tr tf 6 ns (unless otherwise specified) Conditions CL 50 pF VCC 2.0V 4.5V 6.0V CL CL CL CL CL CL 50 pF 150 pF 50 pF 150 pF 50 pF 150 pF 1 k: 50 pF 150 pF 50 pF 150 pF 50 pF 150 pF 1 k: 50 pF 2.0V 2.0V 4.5V 4.5V 6.0V 6.0V 2.0V 4.5V 6.0V 2.0V 4.5V 6.0V 50 80 21 30 19 26 50 21 19 150 200 30 40 26 35 150 30 26 50 9 9 5 5 5 30 9 8 25 7 6 80 16 14 60 12 10 1000 500 400 30 50 5 10 10 10 CPD VCC2f  ICC VCC, and the no load dynamic current consumption, Symbol fMAX Parameter Maximum Operating Frequency TA Typ 2 5 qC 6 30 35 TA 40 to 85qC TA 55 to 125qC Guaranteed Limits 5 24 28 225 288 45 57 39 50 189 250 37 50 31 44 189 37 31 60 13 11 30 5 5 100 20 18 75 15 13 1000 500 400 4 20 23 270 345 48 69 46 60 225 300 45 60 39 53 225 45 39 75 15 13 5 5 5 120 24 20 90 18 15 1000 500 400 Units MHz MHz MHz ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns ns pF pF pF tPHL, tPLH Maximum Propagation Delay, Clock to Q 2.0V 2.0V 4.5V 4.5V 6.0V 6.0V 68 110 22 30 20 28 180 230 36 46 31 40 tPZH, tPZL Maximum Output Enable Time RL CL CL CL CL CL CL tPHZ, tPLZ Maximum Output Disable Time tS Minimum Setup Time RL CL tH Minimum Hold Time 2.0V 4.5V 6.0V tW Minimum Pulse Width 2.0V 4.5V 6.0V tTHL, tTLH Maximum Output Rise and Fall Time tr , tf Maximum Input Rise and Fall Time, Clock CPD Power Dissipation Capacitance (Note 5) CIN Maximum Input Capacitance CL 50 pF 2.0V 4.5V 6.0V 2.0V 4.5V 6.0V (per flip-flop) OC OC VCC GND Note 5: CPD determines the no load dynamic power consumption, PD IS CPD VCC f  ICC. www.fairchildsemi.com 4 MM74HC374 Physical Dimensions inches (millimeters) unless otherwise noted 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide Package Number M20B 5 www.fairchildsemi.com MM74HC374 Physical Dimensions inches (millimeters) unless otherwise noted (Continued) 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide Package Number M20D www.fairchildsemi.com 6 MM74HC374 Physical Dimensions inches (millimeters) unless otherwise noted (Continued) 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Package Number MTC20 7 www.fairchildsemi.com MM74HC374 3-STATE Octal D-Type Flip-Flop Physical Dimensions inches (millimeters) unless otherwise noted (Continued) 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Package Number N20A Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and Fairchild reserves the right at any time without notice to change said circuitry and specifications.
