NLV74HC238ADTR2G

MC74HC238A 1-of-8 Decoder/ Demultiplexer High−Performance Silicon−Gate CMOS The MC74HC238A is identical in pinout to the LS238. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC238A decodes a three−bit Address to one−of−eight active−high outputs. This device features three Chip Select inputs, two active−low and one active−high to facilitate the demultiplexing, cascading, and chip−selecting functions. The demultiplexing function is accomplished by using the Address inputs to select the desired device output; one of the Chip Selects is used as a data input while the other Chip Selects are held in their active states. www.onsemi.com MARKING DIAGRAMS 16 SOIC−16 D SUFFIX CASE 751B 16 1 1 16 Features • • • • • • • • • HC238AG AWLYWW Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS and TTL Operating Voltage Range: 2.0 V to 6.0 V Low Input Current: 1.0 mA High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard No. 7A Chip Complexity: 100 FETs or 29 Equivalent Gates NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These are Pb−Free Devices* 16 1 TSSOP−16 DT SUFFIX CASE 948F HC 238A ALYWG G 1 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) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet. *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. © Semiconductor Components Industries, LLC, 2013 January, 2018 − Rev. 5 1 Publication Order Number: MC74HC238A/D MC74HC238A A0 A0 1 16 VCC A1 2 15 Y0 A2 3 14 Y1 CS2 4 13 Y2 CS3 5 12 Y3 CS1 6 11 Y4 Y7 7 10 Y5 GND 8 9 Y6 ADDRESS INPUTS A1 A2 CS1 CHIPSELECT INPUTS CS2 CS3 Figure 1.

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 VCC). Unused outputs must be left open. MC74HC238A DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC V Guaranteed Limit −55°C to 25°C v 85°C v 125°C Unit VIH Minimum High−Level Input Voltage Vout = 0.1 V or VCC – 0.1 V |Iout| v 20 mA 2.0 3.0 4.5 6.0 1.5 2.1 3.15 4.2 1.5 2.1 3.15 4.2 1.5 2.1 3.15 4.2 V VIL Maximum Low−Level Input Voltage Vout = 0.1 V or VCC – 0.1 V |Iout| v 20 mA 2.0 3.0 4.5 6.0 0.5 0.9 1.35 1.8 0.5 0.9 1.35 1.8 0.5 0.9 1.35 1.8 V VOH Minimum High−Level Output Voltage Vin = VIH or VIL |Iout| v 20 mA 2.0 4.5 6.0 1.9 4.4 5.9 1.9 4.4 5.9 1.9 4.4 5.9 V Vin = VIH or VIL |Iout| v 2.4 mA |Iout| v 4.0 mA |Iout| v 5.2 mA 3.0 4.5 6.0 2.48 3.98 5.48 2.34 3.84 5.34 2.20 3.70 5.20 Vin = VIH or VIL |Iout| v 20 mA 2.0 4.5 6.0 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 Vin = VIH or VIL |Iout| v 2.4 mA |Iout| v 4.0 mA |Iout| v 5.2 mA 3.0 4.5 6.0 0.26 0.26 0.26 0.33 0.33 0.33 0.40 0.40 0.40 Symbol Parameter Test Conditions ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ VOL Maximum Low−Level Output Voltage V Iin Maximum Input Leakage Current Vin = VCC or GND 6.0 ± 0.1 ± 1.0 ± 1.0 mA ICC Maximum Quiescent Supply Current (per Package) Vin = VCC or GND Iout = 0 mA 6.0 4 40 160 mA AC ELECTRICAL CHARACTERISTICS (CL = 50 pF, Input tr = tf = 6.0 ns) Symbol Parameter Guaranteed Limit VCC V −55°C to 25°C v 85°C v 125°C Unit tPLH, tPHL Maximum Propagation Delay, Input A to Output Y (Figures 3 and 6) 2.0 3.0 4.5 6.0 135 90 27 23 170 125 34 29 205 165 41 35 ns tPLH, tPHL Maximum Propagation Delay, CS1 to Output Y (Figures 4 and 6) 2.0 3.0 4.5 6.0 110 85 22 19 140 100 28 24 165 125 33 28 ns tPLH, tPHL Maximum Propagation Delay, CS2 or CS3 to Output Y (Figures 5 and 6) 2.0 3.0 4.5 6.0 120 90 24 20 150 120 30 26 180 150 36 31 ns tTLH, tTHL Maximum Output Transition Time, Any Output (Figures 4 and 6) 2.0 3.0 4.5 6.0 75 30 15 13 95 40 19 16 110 55 22 19 ns − 10 10 10 pF Cin Maximum Input Capacitance Typical @ 25°C, VCC = 5.0 V CPD 55 Power Dissipation Capacitance (Per Package)* * Used to determine the no−load dynamic power consumption: P D = CPD VCC2 f + ICC VCC . www.onsemi.com 4 pF MC74HC238A SWITCHING WAVEFORMS VALID INPUT A VCC 50% OUTPUT Y VCC 90% 50% 10% INPUT CS1 GND GND tPLH tPHL tPHL tPLH tf tr VALID 50% 90% 50% 10% OUTPUT Y tTHL tTLH Figure 4.
