Description

The CD74HC688E is designed as one kind of high-speed CMOS logic 8-bit magnitude comparator that can be used in computer and logic applications (require the comparison of two 8-bit binary words).

Features of the CD74HC688E are:(1)cascadable;(2)wide operating temperature range: -55 to +125 ;(3)balanced propagation delay and transition times;(4)significant power reduction compared to LSTTL logic ICs;(5)alternate source is philips/signetics;(6)High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V;(7)fanout (over temperature range): standard outputs is 10 LSTTL loads and bus driver outputs is 15 LSTTL loads.

The absolute maximum ratings of the CD74HC688E 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.
