MM54C157/MM74C157 Quad 2-Input Multiplexers

General Description

Features

Supply voltage range

3V to 15V

0.45 V (typ.)

These multiplexers are monolithic complementary MOS

(CMOS) integrated circuits constructed with N- and P-chan-

nel enhancement transistors. They consist of four 2-input

multiplexers with common select and enable inputs. When

the enable input is at logical ‘‘0’’ the four outputs assume

the values as selected from the inputs. When the enable

input is at logical ‘‘1’’, the outputs assume logical ‘‘0’’. Se-

lect decoding is done internally resulting in a single select

input only.

High noise immunity

Low power

50 nW (typ.)

Tenth power TTL compatible

Drive 2 LPTTL loads
