These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The maximum package power dissipation is calculated using a junction temperature of 150_C and a board trace length of 750 mils, except for the NT package, which has a trace length of zero. recommended operating conditions 2 VCC Supply voltage VIH High-level input voltage VIL Low-level input voltage VI Input voltage VO Output voltage IOH High-level output current IOL Low-level output current Dt/Dv Input transition rise or fall rate TA Operating free-air temperature MIN NOM MAX 4.5 5 5.5 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 UNIT V V 0.8 V 0 VCC V 0 VCC V −24 mA 24 mA 0 10 ns/V −40 85 °C 74ACT11240 OCTAL BUFFER/LINE DRIVER WITH 3-STATE OUTPUTS SCAS210A − MAY 1987 − REVISED APRIL 1996 electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS VCC IOH = −50 50 mA A VOH 24 mA IOH = −24 IOH = −75 mA{ TYP MAX IOL = 24 mA MIN 4.5 V 4.4 4.4 5.5 V 5.4 5.4 4.5 V 3.94 3.8 5.5 V 4.94 4.8 5.5 V IOL = 50 mA A VOL TA = 25°C MIN MAX UNIT V 3.85 4.5 V 0.1 5.5 V 0.1 0.1 0.1 4.5 V 0.36 0.44 5.5 V 0.36 0.44 V IOL = 75 mA{ 5.5 V IOZ VO = VCC or GND 5.5 V ±0.5 ±5 mA II VI = VCC or GND 5.5 V ±0.1 ±1 mA ICC VI = VCC or GND, IO = 0 5.5 V 8 80 mA DICC‡ One input at 3.4 V, Other inputs at GND or VCC 5.5 V 0.9 1 mA Ci VI = VCC or GND 5V 4 pF Co VI = VCC or GND 5V 10 pF 1.65 † Not more than one output should be tested at a time, and the duration of the test should not exceed 10 ms. ‡ This is the increase in supply current for each input that is at one of the specified TTL voltage levels rather than 0 V or V .

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
