Product details

Dual 4-input AND gate in 14-TSSOP

The 74VHC21FT is a dual 4-input AND gate from Toshiba's 74VHC series, packaged in a 14-TSSOP (0.173", 4.40mm width) surface-mount package. It operates from 2V to 5.5V and delivers a maximum propagation delay of 7ns at 5V with a 50pF load. Each of the two independent AND gates has four inputs, and the device can source or sink 8mA per output. Quiescent current is a maximum of 2µA, making it suitable for battery-powered or low-power logic chains.

Temperature range and output drive

The input logic thresholds are specified as 0.5V to 1.65V for low and 1.5V to 3.85V for high, which scale with the supply rail. The 8mA output drive at both high and low states is typical for the VHC family and is sufficient for driving CMOS inputs on the same board or short PCB traces. For longer runs or higher fan-out, a buffer stage may be needed.

The supplier device package is 14-TSSOPB.

Frequently asked questions

What is the difference between the 74VHC21FT and the 74VHC08FT?

Both are AND gates from the same 74VHC family. The 74VHC21FT has two 4-input gates, while the 74VHC08FT has four 2-input gates. The 74VHC21FT also has a wider temperature range (-40 to 125°C vs -40 to 85°C). The packages are both 14-TSSOP, but pinouts differ due to the different gate configurations.
