FEATURES
DESCRIPTION
• Edge–triggered D–type inputs
• Buffered positive edge–triggered clock
• Buffered common enable input
• True and complementary outputs
• Offers light loading PNP inputs (IIL = –20µA)
TYPE
74F379A
The 74F379A is a 4–bit register with buffered common
enable (E). This device is similar to the 74F175A but
features the common enable rather than common master
reset.

Notes to DC electrical characteristics
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.
