MC74HCT595A 8-Bit Serial-Input/Serial or Parallel-Output Shift Register with Latched 3-State Outputs and LSTTL Compatible Inputs http://onsemi.com MARKING DIAGRAMS High−Performance Silicon−Gate CMOS The MC74HCT595A consists of an 8−bit shift register and an 8−bit D−type latch with three−state parallel outputs. The shift register accepts serial data and provides a serial output. The shift register also provides parallel data to the 8−bit latch. The shift register and latch have independent clock inputs. This device also has an asynchronous reset for the shift register. The HCT595A directly interfaces with the SPI serial data port on CMOS MPUs and MCUs. The device inputs are compatible with standard CMOS or LSTTL outputs. • • • 16 1 Output Drive Capability: 15 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 4.5 to 5.5 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: 328 FETs or 82 Equivalent Gates Improvements over HC595 / HCT595 − Improved Propagation Delays − 50% Lower Quiescent Power − Improved Input Noise and Latchup Immunity Pb−Free Packages are Available* HCT595AG AWLYWW 1 16 16 1 Features • • • • • • 16 SOIC−16 D SUFFIX CASE 751B HCT 595A ALYWG G TSSOP−16 DT SUFFIX CASE 948F 1 A WL, L YY, Y WW, W G, G = Assembly Location = Wafer Lot = Year = Work Week = 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, 2011 March, 2011 − Rev. 1 1 Publication Order Number: MC74HCT595A/D MC74HCT595A LOGIC DIAGRAM PIN ASSIGNMENT SERIAL DATA INPUT A 15 14 1 2 QB 1 16 VCC 3 QC 2 15 QA 4 QD 3 14 A QE 4 13 OUTPUT ENABLE QF 5 12 LATCH CLOCK QG 6 11 SHIFT CLOCK QH 7 10 RESET GND 8 9 SQH SHIFT REGISTER LATCH 5 6 7 SHIFT 11 CLOCK 10 RESET LATCH 12 CLOCK OUTPUT 13 ENABLE 9 QA QB QC QD QE PARALLEL DATA OUTPUTS QF QG QH SQH SERIAL DATA OUTPUT VCC = PIN 16 GND = PIN 8 ORDERING INFORMATION Package Shipping† MC74HCT595ADG SOIC−16 (Pb−Free) 48 Units / Rail MC74HCT595ADR2G SOIC−16 (Pb−Free) 2500 Tape & Reel MC74HCT595ADTG TSSOP−16* 96 Units / Rail MC74HCT595ADTR2G TSSOP−16* (Pb−Free) 2500 Tape & Reel Device †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. *This package is inherently Pb−Free. http://onsemi.com 2 MC74HCT595A ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ MAXIMUM RATINGS Symbol Parameter Value Unit – 0.5 to + 7.0 V VCC DC Supply Voltage (Referenced to GND) Vin DC Input Voltage (Referenced to GND) – 0.5 to VCC + 0.5 V Vout DC Output Voltage (Referenced to GND) – 0.5 to VCC + 0.5 V Iin DC Input Current, per Pin ± 20 mA Iout DC Output Current, per Pin ± 35 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 TL Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP, SOIC or TSSOP Package) SOIC Package† TSSOP Package† _C 260 Stresses exceeding Maximum Ratings may damage the device.

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.
