TECHNICAL DATA DUAL D FLIP-FLOP WITH SET AND RESET IN74VHC74 IN74VHC74 is high-speed logic IC made by CMOS technology and designed for use in high-performance calculating systems with a wide supply voltage range. As for operation speed, IN74VHC74 can be compared with equivalent bipolar ICs based on Schottky TTL and two times surpasses ICs of IN74НС series. IN74VHC74 tolerates operation under conditions when voltage on input is exceeded up to 7V without affecting characteristics and IC reliability. This possibility allows to use IN74VHC74 in radio-electronic devices for interfacing with supply voltages 5V and 3V, eliminate IC failure under supply voltage source emergency outage. Use of output edge shaping block in the microcircuit allows to reduce noise amplitude of noises when switching outputs into the same state simultaneously. Input and output levels of IN74VHC74 are compatible with CMOS levels ORDERING INFORMATION IN74VHC74N Plastic IN74VHC74D SOIC TA = -40° to 85° C for all packages Features: • Supply voltage range 2.0 to 5.5 V. • Output current 8 mA. • Low consumption current: 0.2 mkA (typical value) at Та = 25 °С. • Latchup current not less than 300 mA at Та = 85 °С. • Tolerable value of static potential not less than 2000 V as per human body model (HBM) and not less than 200 V as per machine model (ММ). • Ambient operation temperature minus 40 to plus 85 °С. • Balanced signal propagation delay. • Ensures voltage exceeding mode on input • Low noise level at the simultaneous switching of outputs in the same state: VOLP = 0.8 V (max). • For pins and functions, compatible with IN74HC74. . . www.datasheet4u.com 1 1 page IN74VHC74 AC electrical characteristics (tLH = tHL = 3.0 ns) Symbol Parameter Test conditions VCC, V CL, pF tPHL, tPLH Propagation delay time VIL = 0 V, when switching "on", VIН= Vcc, "off" from input СР to outputs Q, Q 3.3 ± 0.3 15 50 Value 25 °C –40 to 85 °C min max min max – 11.9 – 14.0 – 15.4 – 17.5 tPHL, tPLH Propagation delay time VIL = 0 V, when switching "on", VIН=Vcc, "off" from input СР to outputs Q, Q 5.0 ± 0.5 15 – 50 – 7.3 8.3 – 8.5 – 10.5 tPHL, tPLH Propagation delay time VIL = 0 V, when switching "on", VIН= Vcc, "off" from inputs SD , RD to outputs Q, Q 3.3 ± 0.3 15 – 12.3 – 14.5 50 – 15.8 – 18.0 tPHL, tPLH Propagation delay time VIL = 0 V, when switching "on", VIН=Vcc, "off" from inputs SD , RD to outputs Q, Q 5.0 ± 0.5 15 – 50 – 7.7 9.7 – 9.0 – 11.0 fmax Maximum Frequency Clock VIL = 0 V, 3.3 ± 0.5 15 – 80 – 70 VIН=Vcc, 50 – 50 – 45 fmax Maximum Frequency Clock VIL = 0 V, 5.0 ± 0.5 15 – 130 – 110 VIН=Vcc, 50 – 90 – 75 tSU Time of setting signal D VIL = 0 to CP VIН=Vcc, tH Retention time, D signal VIL = 0 to CP VIН=Vcc, tREM Time of recovery of VIL = 0 signal СР after signals VIН=Vcc, SD , RD V, 3.3 ± 0.3 5.0 ± 0.5 V, 3.0 ± 0.3 5.0 ± 0.5 V, 3.0 ± 0.3 5.0 ± 0.5 15 - 50 15 - 50 15 - 50 tW Pulse duration of CP, VIL = 0 V, 3.0 ± 0.3 15 - SD , RD signals VIН=Vcc, 5.0 ± 0.5 50 CI Input capacity CРD Dynamic capacity VI = 0 V orVCC 5.0 5.0 6.0 5.0 0.5 0.5 5.0 3.0 6.0 5.0 – – – – – – – – 10 50 7.0 5.0 0.5 0.5 5.0 3.0 7.0 6.0 – – – – – – – – Unit ns ns ns ns MHz MHz ns pF 5 5 Page
