The CD74HCT00MT is a quad 2-input NAND gate from the 74HCT logic family.
The 20 ns max propagation delay at 4.5 V and 50 pF load sets the gate's contribution to the critical path.
A close functional equivalent is the SN74LV00APWR from TI, which is a quad 2-input NAND gate in a TSSOP package. The LV00 runs from 2 V to 5.5 V, has a faster 7.5 ns propagation delay at 5 V, but has a narrower temperature range (-40°C to 85°C) versus the -55°C to 125°C range of the CD74HCT00MT. The SN74F00DR is a 5 V-only option with 5 ns delay but commercial temperature only (0°C to 70°C).
