21996 Mar 12 853–0026 16555
FEATURES
- High impedance inputs for reduced loading (20µA in Low and High states)
- Ideal for addressable register applications
- Enable for address and data synchronization applications
- Eight edge–triggered D–type flip–flops
- Buffered common clock
- See ’F273A for Master Reset version
- See ’F373 for transparent latch version
- See ’F374 for 3–State version
DESCRIPTION
The 74F377A has 8 edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common buffered clock (CP) input loads all flip-flops simultaneously when the Enable (E) input is Low. The register is fully edge triggered. The state of each D input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop’s Q output. The E input must be stable one setup time prior to the Low-to-High clock transition for predictable operation. TYPE TYPICAL fMAX TYPICAL SUPPLY CURRENT (TOTAL) 74F377A 165MHz 29mA

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. To reduce the effect of external noise during test. Special test conditions are not necessary for the ’377A. 4. 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.
