SN74HC02-Q1: input and output drive configuration(CMOS/ Pushpull CMOS) and drain to source ON resistance of CMOS configuration

SANAM HIMAJA

Part Number: SN74HC02-Q1

What is the input and output drive configuration (CMOS/ Pushpull CMOS) of "SN74HC02-Q1" logic gate? and What is the drain to source ON resistance of CMOS configuration (Input and Output)?

Everything is CMOS; see HCMOS Design Considerations.

The worst-case output impedance can be computed from the V_OL/V_OH specifications in the datasheet: 0.4 V / 5.2 mA ≈ 77 Ω (at V_CC = 6 V).

The inputs are connected to the gates, so the input impedance is approximately inifinite.

You could also consider the newly released HCS family of devices and is P2P with the HC02-Q1.
