FAST AND LS TTL DATA

DUAL 4-INPUT MULTIPLEXER

The SN54 / 74LS352 is a very high-speed Dual 4-input Multiplexer with

Common Select inputs and individual Enable inputs for each section. It can

select two bits of data from four sources. The two buffered outputs present

data in the inverted (complementary) form. The SN54/ 74LS352 is the func-

tional equivalent of the SN54/ 74LS153 except with inverted outputs.
