FEATURES
· Edgetriggered Dtype inputs · Buffered positive edgetriggered clock · Buffered common enable input · True and complementary outputs · Offers light loading PNP inputs (IIL = 20µA)
TYPE 74F379A TYPICAL fmax 200MHz
DESCRIPTION
The 74F379A is a 4bit register with buffered common enable (E). This device is similar to the 74F175A but features the common enable rather than common master reset.
TYPICAL SUPPLY CURRENT (TOTAL) 29mA

ICC Supply current (total) 29 42 mA 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.
