Standard Logic

We offer an extensive portfolio of standard logic ICs and high-speed CMOS FCT, LVC, and ALVC solutions for high-performance, low-voltage computing and communications systems. Our Fast CMOS Technology (FCT) line features octal line drivers, 16-bit buffers, bi-directional bus transceivers, latches, multiplexers, and high-speed comparators—ideal for high-current drive bus interface applications. Low-voltage CMOS (LVC) products support 5V tolerance, hot insertion, and 3.3V/2.5V operation, with features such as buffer drivers, bus transceivers, latches, and universal bus transceivers. Renesas Advanced Low-Voltage CMOS (ALVC) products are optimized for high-speed computing and include buffer drivers, latches, and transceivers.

About Bus Transceivers

Bus transceivers utilize CMOS logic gates to enable smooth data flow within a system, allowing communication between data buses. They are commonly used for two-way data transmission between internal memory and processing device buses or between internal and external device buses. Bus transceivers are available in synchronous or asynchronous configurations. Synchronous bus transceivers transmit data in a continuous stream. Asynchronous devices send data in smaller, variable-sized groups. Serial bus transceivers transmit one bit at a time, while parallel bus transceivers handle multiple bits simultaneously. We offer bus transceivers in 8-, 16-, and 32-bit configurations with two- or three-state outputs, 5V input tolerance, and bus-hold capabilities.

About Digital High-speed Comparators

Digital high-speed comparators, built with a reliable architecture using high-speed CMOS logic gates, compare two bit strings and determine if they are identical. Our 74FCT521T 8-bit identity comparator is manufactured with advanced, dual-metal, high-speed CMOS technology. These comparators can evaluate two 8-bit words and generate a low output when all bits match exactly. Additionally, the IA = B expansion input functions as an active-low enable input.

About Line Drivers (Digital)

A digital line driver enhances the quality of a digital signal over long cable runs by increasing the signal's voltage at its source to better "drive" the transmission line. Built with high-speed CMOS logic gates, the 74FCT162244T is a 16-bit line driver designed for bus interface or signal buffering applications requiring high speed and low power consumption. These devices feature a flow-through pin organization and compact packaging to simplify board layouts. Inputs are equipped with hysteresis to improve noise margins, while three-state controls enable independent 4-bit, 8-bit, or 16-bit operation. The line driver is ideal for low-noise, point-to-point applications with a single receiver or light lumped loads (<200pF). Designed to limit output current, these drivers minimize noise and ringing on signal lines without requiring external series terminating resistors.
