4 / 27 page SN54AHC540, SN74AHC540 SCLS260L – DECEMBER 1995 – REVISED OCTOBER 2015 www.ti.com 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VCC Supply voltage range –0.5 7 V VI Input voltage range(2) –0.5 7 V VO Output voltage range(2) –0.5 VCC + 0.5 V IIK Input clamp current VI < 0 –20 mA IOK Output clamp current VO < 0 or VO > VCC ±20 mA IO Continuous output current VO = 0 to VCC ±25 mA Continuous current through VCC or GND ±75 mA TJ Junction temperature 150 °C Tstg Storage temperature –65 150 °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. 6.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) 1000 Electrostatic V(ESD) V Charged device model (CDM), per JEDEC specification JESD22-C101, all discharge 2000 pins(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) SN54AHC540 SN74AHC540 UNIT MIN MAX MIN MAX VCC Supply voltage 2 5.5 2 5.5 V VCC = 2 V 1.5 1.5 VIH High-level input voltage VCC = 3 V 2.1 2.1 V VCC = 5.5 V 3.85 3.85 VCC = 2 V 0.5 0.5 VIL Low-level Input voltage VCC = 3 V 0.9 0.9 V VCC = 5.5 V 1.65 1.65 VI Input voltage 0 5.5 0 5.5 V VO Output voltage 0 VCC 0 VCC V VCC = 2 V –50 –50 µA IOH High-level output current VCC = 3.3 V ± 0.3 V –4 –4 mA VCC = 5 V ± 0.5 V –8 –8 VCC = 2 V 50 50 µA IOL Low-level output current VCC = 3.3 V ± 0.3 V 4 4 mA VCC = 5 V ± 0.5 V 8 8 VCC = 3.3 V ± 0.3 V 100 100 Δt/Δv Input transition rise or fall rate ns/V VCC = 5 V ± 0.5 V 20 20 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.
