INTEGRATED CIRCUITS 74F398*, 74F399 Registers * Discontinued part. Please see the Discontinued Product List. Product specification Supersedes data of 1990 Apr 08 IC15 Data Handbook 1999 Jan 08 Philips Semiconductors Product specification Registers 74F398*,74F399 74F398 Quad 2-Port Register with True and Complementary Outputs 74F399 Quad 2-Port Register FEATURES PIN CONFIGURATION – 74F398 • Select inputs from two data sources • Fully positive edge-triggered • Both True and Complementary outputs–74F398 DESCRIPTION The 74F398 and 74F399 are the logical equivalent of a quad 2-input multiplexer feeding into four edge-triggered flip-flops. A common Select input determines which of two 4-bit words is accepted. The selected data enters the flip-flops on the rising edge of the clock. The 74F399 is the 16-pin version of the 74F398, with only the true (Qn) outputs of the flip-flops available. The 74F398 and 74F399 are high speed quad 2-port registers. They select 4 bits of data from either of two sources (Ports) under control of a common select input (S). The selected data is transferred to a 4-bit output register synchronous with the Low-to-High transition of the Clock input (CP). The 4-bit D-type output register is fully edge-triggered. The Data inputs (I0n, I1n) and Select input (S) must be stable only a setup time prior to and hold time after the Low-to-High transition of the Clock input for predictable operation. The 74F398 has both Q and Q outputs.

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. * Discontinued part.
