74F350
4-bit shifter

March 20, 1989

FEATURES
Shifts 4 bits of data to 0, 1, 2, 3 places under control of two
select lines
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.
