Logic - Specialty Logic

74ABT899A,623 is an advanced low power 8-bit CMOS buffer/logic circuit module. It is based on a configurable logic family of products from Philips Semiconductors. It features an on-chip logic cell array configurable to a variety of logic functions and a wide range of output latch, flip-flop and open collector types. The 74ABT899A,623\'s low power consumption makes it ideal for portable applications, where its reduced power demands, combined with its on-chip flexibility, make it a popular choice.

The 74ABT899A,623 is built on a basic module that contains 4 or 8 input/output pins and a logic cell array. The logic cell array contains 4 logic elements, 8 flip-flops and 8 output pins. Each logic element is a two-input logic gate. The logic gate may be AND gate, OR gate, inverter, or NOT gate. The logic gates are configurable. Flip-flops can be used as registers or as part of a state machine. The 74ABT899A,623 module is also capable of performing arithmetic, such as addition, subtraction and multiplication.

The 74ABT899A,623 module is widely used in a variety of applications, from high speed data acquisition and control systems to low power consumption products for battery-operated devices. It is ideal for applications in which functions must be realized quickly, while still meeting the power saving requirements.

The 74ABT899A,623 operates with a 3.3 to 5.5 volt supply range. It uses 0.5 microamperes (mA) of active current and 10 microamperes (uA) of standby current, which makes it suitable for low voltage, low power applications. The power-down mode requires a supply current less than 10 microamperes (uA). The 74ABT899A,623 has a propagational delay of 8 nanoseconds (ns) and a propagation-delay-through of 2.4 nanoseconds (ns).

The main advantages of the 74ABT899A,623 module include its flexible I/O configurations, configurable logic cell array, low power consumption, high speed operation and low propagation delay. The ability to be configured to a variety of logic functions, using the combination of logic functions and flip-flops makes the 74ABT899A,623 module suitable for applications in which multiple operations must be performed quickly.

Working Principle
