• 74F456 combines 74F244 and 74F280A functions in one package
• 74F456 is a center pin version of the 74F656A
• Non-Inverting
• 3-State outputs sink 64mA and source 15mA
• 24-pin plastic Slim DIP (300 mil) package
• Broadside pinout simplifies PC board layout

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at VCC = 5V, Tamb = 25°C.
3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, IOS tests should be performed last.
