MC74VHCT374A Octal D-Type Flip-Flop with 3-State Output The MC74VHCT374A is an advanced high speed CMOS octal flip−flop with 3−state output fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. This 8−bit D−type flip−flop is controlled by a clock input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3 V to 5.0 V, because it has full 5.0 V CMOS level output swings. The VHCT374A input and output (when disabled) structures provide protection when voltages between 0 V and 5.5 V are applied, regardless of the supply voltage. These input and output structures help prevent device destruction caused by supply voltage−input/output voltage mismatch, battery backup, hot insertion, etc. http://onsemi.com MARKING DIAGRAMS 20 1 • • High Speed: fmax = 140 MHz (Typ) at VCC = 5.0 V Low Power Dissipation: ICC = 4 mA (Max) at TA = 25°C TTL−Compatible Inputs: VIL = 0.8 V; VIH = 2.0 V Power Down Protection Provided on Inputs and Outputs Balanced Propagation Delays Designed for 4.5 V to 5.5 V Operating Range Low Noise: VOLP = 1.6 V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300 mA ESD Performance: Human Body Model > 2000 V; Machine Model > 200 V Chip Complexity: 276 FETs or 69 Equivalent Gates These Devices are Pb−Free and are RoHS Compliant 1 20 1 Features • • • • • • • • • • VHCT374A AWLYYWWG SOIC−20WB SUFFIX DW CASE 751D VHCT 374A ALYWG G TSSOP−20 SUFFIX DT CASE 948E 1 A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week G or G = Pb−Free Package (Note: Microdot may be in either location) FUNCTION TABLE INPUTS OE L L L H OUTPUT CP D Q L, H, X H L X X H L No Change Z ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 4 of this data sheet. © Semiconductor Components Industries, LLC, 2014 October, 2014 − Rev. 6 1 Publication Order Number: MC74VHCT374A/D MC74VHCT374A DATA INPUTS 2 5 6 9 12 15 16 19 3 D0 4 D1 7 D2 8 D3 13 D4 14 D5 17 D6 18 D7 11 CP OE Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 NONINVERTING OUTPUTS 1 OE 1 20 VCC Q0 2 19 Q7 D0 3 18 D7 D1 4 17 D6 Q1 5 16 Q6 Q2 6 15 Q5 D2 7 14 D5 D3 8 13 D4 Q3 9 12 Q4 10 11 CP GND Figure 2.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V CC ). Unused outputs must be left open. Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. †Derating − SOIC Packages: – 7 mW/_C from 65_ to 125_C TSSOP Package: − 6.1 mW/_C from 65_ to 125_C ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ RECOMMENDED OPERATING CONDITIONS Symbol Parameter VCC DC Supply Voltage Vin DC Input Voltage Vout DC Output Voltage TA Operating Temperature tr, tf Input Rise and Fall Time Outputs in 3−State High or Low State VCC =5.0V ±0.5V Min Max Unit 4.5 5.5 V 0 5.5 V 0 0 5.5 VCC V − 40 + 85 _C 0 20 ns/V Functional operation above the stresses listed in the Recommended Operating Ranges is not implied.
