The ISL55100BIRZ is a low-power single-port logic gate designed for logic interface applications in low voltage systems where very low quiescent current and ultra small physical size are critical. The ISL55100BIRZ operates on a typical logic-level voltage range of up to 10.0V on its logic inputs and produces an output voltage compatible with TTL systems.

The ISL55100BIRZ is used in a variety of applications, such as linear and digital logic interface. The single-port logic gate is perfect for interfacing with digital and analog systems, product recognition systems and any other type of process requiring logic-level logic gates. The ISL55100BIRZ is used most commonly in digital logic data acquisition, telecommunication and instrumentation applications.

Logic Specification

The ISL55100BIRZ logic IC is designed in a single-port configuration containing two 4-input NAND gates, a latch, and an inverter. The operating characteristics of the ISL55100BIRZ are listed in the following table.

The ISL55100BIRZ has a die size of 1.3mm x 1.3mm and is offered in an 8-pin SON package or a low-noise wafer level chip scale package (WLCSP) for minimum space requirements. The WLCSP package uses the industry standard 2 mm x 2 mm, four-pin plus centre pad footprint to save the greatest amount of board space.

Working Principle

The working principle of the ISL55100BIRZ is based on NAND, latch, and inverter gates. When power with the appropriate voltage is applied to the gates, the corresponding gates will operate accordingly. When the appropriate outputs are enabled and driven, the NAND gates will produce an output voltage, and the inverters will produce an output compatible with TTL level systems.

The logic IC helps improve the operational speed by producing logic-level signals with low quiescent current and ultra-fast response time. The NAND and inverters output signals are transmitted to the next component in the logic chain, which can process the signals and produce an appropriate response.

Conclusion

The ISL55100BIRZ is an ideal single-port logic gate for interface applications in low voltage systems where limited space is a requirement. It is used in many applications such as linear and digital logic interfaces and in instrumentation, telecommunication, product recognition, and digital logic data acquisition. The logic IC contains two 4-input NAND gates, a latch and an inverter, which produces the necessary output signals with low quiescent current and quick response time.
