LVC family overview

The LVC family stands out as the logic industry standard for 3.3V applications in both the telecom and the EDP markets. Also, its 5V tolerance makes it extremely attractive for mixed 5V/3V systems. At the same time, LVC is ideal for most consumer and personal electronic applications.

NXP LVC family provides the low power consumption of CMOS, offers direct LVTTL level interfacing, supports live insertion, and is guaranteed for industrial operating temperatures. The family also provides 4.5ns-5ns speeds and 24mA drive capability while operating at 3V with very low static and dynamic power consumption.

Designers may also choose the bus hold and/or damping resistor options. The bus hold circuitry eliminates the need for pull-up or pull-down resistors for floating inputs, and the series damping resistors help prevent signal undershoot and overshoot.

The LVC family is an excellent, cost effective solution for migrating from 5V HCMOS, ACT, and FAST into a new low-power, low-voltage system. The product family offerings range from standard gates and octals to complex 16-bit bus interface functions used for buffering, multiplexing, and interfacing in mixed 5V/3V systems.
