54HC154中文资料SS数据手册PDF规格书

描述 Description

The 54HC154 is fabricated using a 2.5μm 5V CMOS

process and has the same high speed performance of

LSTTL combined with CMOS low power consumption. The

device consists of x4 active-high binary address inputs, x16

active-low outputs & x2 active-low chip-selects. The x2

active-low chip-selects can be used to strobe & eliminate

normal decoding ‘glitches’ on the outputs, or can be used to

expand the decoder. Both chip-selects must be low to

enable the outputs. The demultiplexing function is executed

by use of one chip-select input as multiplexed data input.

When the other chip-select input is low, the addressed

output will follow the state of the applied data.

Features:

 Output Drive Capability: 10 LSTTL Loads

 Low Input Current: 1μA

 Outputs directly interface CMOS, NMOS and TTL

 Operating Voltage Range: 2V to 6V

 CMOS High Noise Immunity

 Function compatible with 54LS154

 Full Military Temperature Range.
