74F350

Philips Semiconductors FAST Products Product specification 4-bit shifter 74F350 FEATURES select lines • Shifts 4 bits of data to 0, 1, 2, 3 places under control of two • 3-State outputs for bus organized systems DESCRIPTION The 74F350 is a combination logic circuit that shifts a 4-bit word from 0 to 3 places. No clocking is required as with shift registers. The 74F350 can be used to shift any number of bits any number of places up or down by suitable interconnection. Shifting can be: 1. Logical — with logic zeros filled in at either end of the shifting field. 2. Arithmetic — where the sign bit is extended during a shift down. 3. End around — where the data word forms a continuous loop. The 3-State outputs are useful for bus interface applications or expansion to a larger number of shift positions in end around shifting. The active Low Output Enable (OE) controls the state of the outputs. The outputs are in the high impedance “off” state when OE is High, and they are active when OE is Low.

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.
