74HCT00PW,118

Overview

The Nexperia 74HCT00PW,118 is a quad 2-input NAND gate belonging to the HCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a TSSOP-14 package (SOT402-1). The device features TTL-compatible input levels and includes internal clamp diodes on inputs. Static characteristics specify a maximum low-level output voltage of 0.4 V at 4 mA load and a high-level output voltage of 3.7 V at -4 mA load under worst-case temperature conditions. Dynamic performance indicates a propagation delay of up to 29 ns at 4.5 V with 50 pF load.
