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.
