The CDx4HC(T)245 is an octal bus transceiver with 3-state outputs. All eight channels are controlled by the direction (DIR) pin and output enable ( OE) pin.

Features

• Buffered inputs

• Three-state outputs

• Bus line driving capability

• Typical propagation delay (A to B, B to A) 9ns at VCC = 5V, CL = 15pF, TA = 25°C

• Fanout (over temperature range)

– Bus driver outputs :15 LSTTL loads

• Wide operating temperature range : -55°C to 125°C

• 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 = 5 V

• 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
