All devices have the ability to drive 10 LSTTL loads. The 74HCT logic family is functionally pin compatible with the standard 74LS logic family. * Typical Propagation Delay: 7ns at VCC = 5V, CL = 15pF, TA = 25oC * Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads * Wide Operating Temperature Range . . . -55oC to 125oC Ordering Information * Balanced Propagation Delay and Transition Times PART NUMBER * Significant Power Reduction Compared to LSTTL Logic ICs * HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V * HCT Types - 4.5V to 5.5V Operation - Direct LSTTL Input Logic Compatibility, VIL= 0.8V (Max), VIH = 2V (Min) * CMOS Input Compatibility, Il 1A at VOL, VOH TEMP.
