MC74VHCT138A 3-to-8 Line Decoder The MC74VHCT138A is an advanced high speed CMOS 3−to−8 decoder fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. When the device is enabled, three Binary Select inputs (A0 − A2) determine which one of the outputs (Y0 − Y7) will go Low. When enable input E3 is held Low or either E2 or E1 is held High, decoding function is inhibited and all outputs go high. E3, E2, and E1 inputs are provided to ease cascade connection and for use as an address decoder for memory systems. 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 they have full 5.0 V CMOS level output swings. The VHCT138A input structures provide protection when voltages between 0 V and 5.5 V are applied, regardless of the supply voltage. The output structures also provide protection when VCC = 0 V. 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 16 SOIC−16 D SUFFIX CASE 751B 1 1 16 • • High Speed: tPD = 7.6 ns (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 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: 122 FETs or 30.5 Equivalent Gates These Devices are Pb−Free and are RoHS Compliant VHCT 138A ALYWG G TSSOP−16 DT SUFFIX CASE 948F 1 1 Features • • • • • • • • • VHCT138AG AWLYWW A = Assembly Location WL, L = Wafer Lot Y = Year WW, W = Work Week G or G = Pb−Free Package (Note: Microdot may be in either location) PIN ASSIGNMENT A0 1 16 VCC A1 2 15 Y0 A2 3 14 Y1 E1 4 13 Y2 E2 5 12 Y3 E3 6 11 Y4 Y7 7 10 Y5 GND 8 9 Y6 ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 5 of this data sheet. © Semiconductor Components Industries, LLC, 2011 May, 2011 − Rev. 4 1 Publication Order Number: MC74VHCT138A/D MC74VHCT138A FUNCTION TABLE Inputs LOGIC DIAGRAM Outputs 15 E3 E2 E1 A2 A1 A0 Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7 X X L X H X H X X X X X X X X X X X H H H H H H H H H H H H H H H H H H H H H H H H H H H H L L L L L L L L L L L L L L H H L H L H L H H H H L H H H H L H H H H L H H H H H H H H H H H H H H H H H H H H L L L L L L L L H H H H L L H H L H L H H H H H H H H H H H H H H H H H L H H H H L H H H H L H H H H L A0 SELECT INPUTS A1 A2 E3 ENABLE INPUTS E2 E1 Y0 14 Y1 13 Y2 12 Y3 11 Y4 10 Y5 9 Y6 7 Y7 1 2 3 6 5 4 H = high level (steady state); L = low level (steady state); X = don’t care EXPANDED LOGIC DIAGRAM 15 14 A0 A1 13 1 12 2 11 A2 3 10 E2 E1 Y1 Y2 Y3 Y4 Y5 5 4 9 7 E3 Y0 6 IEC LOGIC DIAGRAM A0 1 A1 2 A2 3 BIN/OCT 1 0 2 4 & E3 6 E2 5 E1 4 EN 15 Y0 A0 1 1 14 Y1 A1 2 2 13 Y2 A2 3 3 12 Y3 4 11 Y4 5 10 Y5 E3 6 6 9 Y6 E2 5 7 7 Y7 E1 4 DMUX 0 0 G 7 2 & http://onsemi.com 2 0 15 Y0 1 14 Y1 2 13 Y2 3 12 Y3 4 11 Y4 5 10 Y5 6 9 Y6 7 7 Y7 Y6 Y7 ACTIVE-LOW OUTPUTS MC74VHCT138A ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ MAXIMUM RATINGS Symbol Value Unit VCC DC Supply Voltage Parameter – 0.5 to + 7.0 V Vin DC Input Voltage – 0.5 to + 7.0 V Vout DC Output Voltage – 0.5 to + 7.0 – 0.5 to VCC + 0.5 V IIK Input Diode Current − 20 mA IOK Output Diode Current (VOUT < GND; VOUT > VCC) ± 20 mA Iout DC Output Current, per Pin ± 25 mA ICC DC Supply Current, VCC and GND Pins ± 75 mA PD Power Dissipation in Still Air, 500 450 mW Tstg Storage Temperature – 65 to + 150 _C VCC = 0 High or Low State SOIC Packages† TSSOP Package† This device contains protection circuitry to guard against damage due to high static voltages or electric fields. 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. Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, 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 ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ 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 Min Max Unit 3.0 5.5 V 0 5.5 V 0 0 5.5 VCC V − 55 + 125 _C 0 20 ns/V VCC = 0 High or Low State VCC =5.0V ±0.5V The qJA of the package is equal to 1/Derating.
