74HCT153DB集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

GENERAL DESCRIPTION

The 74HC/HCT153 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.

The 74HC/HCT153 have two identical 4-input multiplexers which select two bits of data from up to four sources selected by common data select inputs (S0, S1). The two 4-input multiplexer circuits have individual active LOW output enable inputs (1E, 2E) which can be used to strobe the

outputs independently. The outputs (1Y, 2Y) are forced LOW when the corresponding output enable inputs are HIGH.

FEATURES

• Non-inverting output

• Separate enable for each output

• Common select inputs

• See ‘253” for 3-state version

• Permits multiplexing from n lines to 1 line

• Enable line provided for cascading(n lines to 1 line)

• Output capability: standard

• ICC category: MSI
