4 / 26 page SN54HC594, SN74HC594 SCLS040G – DECEMBER 1982 – REVISED MARCH 2015 www.ti.com 6 Specifications 6.1 Absolute Maximum Ratings (1) over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VCC Supply voltage –0.5 7 V IIK Input clamp current(2) VI < 0 or VI > VCC –20 20 mA IOK Output clamp current(2) VO < 0 or VO > VCC –20 20 mA IO Continuous output current VO = 0 to VCC –35 35 mA Continuous current through VCC or GND –70 70 mA D package 73 θJA Package thermal impedance(3) DW package 57 °C/W N package 67 Tstg Storage temperature –60 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The input and output voltage ratings may be exceeded if the input and output current ratings are observed. (3) The package thermal impedance is calculated in accordance with JESD 51-7. 6.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V(ESD) Electrostatic discharge V Charged-device model (CDM), per JEDEC specification JESD22- ±1000 C101(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) (1) SN54HC594(2) SN74HC594 UNIT MIN NOM MAX MIN NOM MAX VCC Supply voltage 2 5 6 2 5 6 V VCC = 2 V 1.5 1.5 VIH High-level input voltage VCC = 4.5 V 3.15 3.15 V VCC = 6 V 4.2 4.2 VCC = 2 V 0.5 0.5 VIL Low-level input voltage VCC = 4.5 V 1.35 1.35 V VCC = 6 V 1.8 1.8 VI Input voltage 0 VCC 0 VCC V VO Output voltage 0 VCC 0 VCC V VCC = 2 V 1000 1000 tt Input transition (rise and fall) rate VCC = 4.5 V 500 500 ns VCC = 6 V 400 400 TA Operating free-air temperature –55 125 –40 125 °C (1) All unused inputs of the device must be held at VCC or GND to ensure proper device operation.
