Toshiba America Electronic Components, Inc. (TAEC) today announced the availability of a line of CMOS logic ICs in small-outline integrated circuit (SOIC) packages: the 74HCxxxD series. These products support flow and reflow soldering, and are suitable for industrial equipment and digital home appliances with logic levels of 6V and lower. The 63 new part numbers in the 74HCxxxD series consist of the most commonly used 74-series logic functions, bringing the total number of CMOS logic ICs offered by Toshiba to more than 300.
An SOIC is a surface-mounted integrated circuit that occupies an area that is approximately 30–50 percent less than an equivalent dual in-line package (DIP) with a thickness that is 70 percent smaller. This smaller size is well suited to applications that require a smaller PCB footprint. Toshiba’s ICs are available in industry standard packages of SOIC14, SOIC16, and SOIC20, and include a range of functionalities such as various gate types, flip flops, buffers, multiplexers, serial/parallel shift registers and more.
Toshiba’s new CMOS logic ICs in SOIC packages are available now.
