Single-gate logic devices shrink and save

World's smallest and thinnest single-gate logic devices save space and reduce power consumption.

Toshiba has introduced what it claims are the world's smallest and thinnest single-gate logic devices.

The new LMOS (Logic-MOS) devices are ideally suited to PDAs, mobile phones and other portable and battery-powered applications where power and space need to be conserved.

Supplied in the new super-miniature style fSV package, devices in the TC7SHxx LMOS family measure just 1.0 x 1.0 x 0.48mm.

As a result, board-mounting area is 76% lower than previous generation USV (SOT-353) alternatives and over 60% lower than miniature ESV packages.

The new TC7SHxx devices operate with a supply voltage between 2 and 5.5V and offer a typical propagation delay of 3.7ns.

Output current for the new parts is rated at 8mA, with power dissipation rated at 50mW.

All devices incorporate input power down protection as standard.

Toshiba's TC7SHxx LMOS line up includes two-input NAND, two-input AND, two-input NOR, two-input OR and two-input EX-OR single-gate logic functions, as well as a variety of inverter and buffer options.

Toshiba's new 5-pin fSV package uses a flat lead design in which the leads are contained within the 1.0 x 1.0mm mounting footprint.

The packages are available with conventional tin-lead plated pins or with lead-free alternatives.
