描述 Description

The ’HC03 and ’HCT03 logic gates utilize silicon gate CMOS

technology to achieve operating speeds similar to LSTTL

gates with the low power consumption of standard CMOS

integrated circuits. All devices have the ability to drive 10

LSTTL loads. The HCT logic family is functionally as well as

pin compatible with the standard LS logic family.

These open drain NAND gates can drive into resistive loads

to output voltages as high as 10V. Minimum values of RL

required versus load voltage are shown in Figure 2.
