Description

The CD74HC138SM is designed as one kind of high speed CMOS logic 3-to-8 line decoder / demultiplexer inverting and non-inverting.

Features of the CD74HC138SM are:(1)select one of eight data outputs active low for 138, active high for 238;(2)l/O port or memory selector;(3)three enable inputs to simplify cascading;(4)wide operating temperature range: -55 to +125 ;(5)balanced propagation delay and transition times;(6)significant power reduction compared to LSTTL logic ICs;(7)alternate source is philips/signetics;(8)High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V;(9)fanout (over temperature range): standard outputs is 10 LSTTL loads and bus driver outputs is 15 LSTTL loads.

The absolute maximum ratings of the CD74HC138SM can be summarized as:(1)DC supply voltage: -0.5V to 7V;(2)DC input diode current for VI < -0.5V or VI > VCC + 0.5V: ±20 mA;(3)DC output diode current for VO < -0.5V or VO > VCC + 0.5V: ±20 mA;(4)DC output source or sink current per output pin for VO > -0.5V or VO < VCC + 0.5V: ±25 mA;(5)DC Vcc or ground current, Icc or IGND: ±50 mA.
