N74F350D中文资料飞利浦数据手册PDF规格书

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.

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
