Philips Semiconductors Product specification 74F378Hex D flip-flop with enable
21989 Oct 05 853–0067 97804
FEATURES
- 6-bit high-speed parallel register
- Positive edge-triggered D-type inputs
- Fully buffered common Clock and Enable inputs
- Input clamp diodes limit high speed termination effects
- Fully TTL and CMOS compatible
DESCRIPTION
The 74F378 has six 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 setup time before the Low-to-High clock transition is transformed to the corresponding flop-flop’s Q output. The E input must be stable one setup time prior to the Low-to-High clock transition for predictable operation. PIN CONFIGURATION 107 VCCE GND CP SF00927 TYPE TYPICAL fmax TYPICAL SUPPLY CURRENT (TOTAL) 74F378 100MHz 35mA

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.
