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.
I1
I2
I3

8
GND
9
S1
2. Arithmetic — where the sign bit is extended during a shift down.
3. End around — where the data word forms a continuous loop.
SF00205
ORDERING INFORMATION
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.

NOTES:
1. 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 V = 5V, T = 25°C.

3. Not more than one output should be shorted at a time. For testing I , the use of high-speed test apparatus and/or sample-and-hold
OS
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, I tests should be performed last.
