CD74HC243E.A规格书详情

1 Features

• Typical propagation delay (A to B, B to A) of 7ns at

VCC = 5 V, CL = 15pF, TA = 25oC

• Three-state outputs

• Buffered inputs

• Fanout (over temperature range)

– Standard outputs : 10 LSTTL loads

– Bus driver outputs : 15 LSTTL loads

• Wide operating temperature range : -55oC to

125oC

• Balanced propagation delay and transition times

• Significant power reduction compared to LSTTL

logic ICs

• HC types

– 2 V to 6 V Operation

– High noise immunity: NIL = 30%, NIH = 30% of

VCC at VCC = 5V

• HCT types

– 4.5 V to 5.5 V operation

– Direct LSTTL input logic compatibility, VIL= 0.8

V (Max), VIH = 2 V (Min)

– CMOS input compatibility, Il ≤ 1μA at VOL, VOH

2 Description

The CDx4HC243 and CDx4HCT243 are quad bus

transceivers with 3-state outputs. The OEA and OEB

inputs control both the high-impedance state as well

as the direction of communication through the device.
