SN54LS352 Datasheet, PDF (1/5 Pages) Motorola, Inc – DUAL 4-INPUT MULTIPLEXER

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.
• Inverted Version of the SN54 / 74LS153
• Separate Enables for Each Multiplexer
• Input Clamp Diode Limit High Speed Termination Effects
