The PCA9514DP,118 is a part of the series of advanced, low-power bidirectional logic level translators. These low-power logic level shifters are designed to interface two voltage levels on bidirectional bus lines with open drain or open collector outputs. The PCA9514DP,118 is capable of translating between TTL and other voltage levels, as well as between different logic standards such as CMOS, AHDL, and PMOS. These low-power logic level shifters can be used in a variety of applications including switches, multiplexers, transducers, and buses.

The PCA9514DP,118 is a dual-channel level translator with one channel in each direction. Each channel externally configurable through the two-bit control register. Each channel can directly drive up to 120mA and can switch between input and output levels. The output slew rate can be adjusted using external resistors.

The PCA9514DP,118 has a variety of features that make it attractive for a wide range of applications. It has a wide operating temperature range from -40°C to +125°C (-40°F to +257°F). It also has an extended voltage range from 1.14V to 4.2V for high performance applications. In addition, it has an extremely low propagation delay of 10ns, low supply current of 3mA, and a low logic 1 level of typically 0.05V.

The PCA9514DP,118 is mainly used as a signal buffer, repeater, or splitter in communication systems, automotive, and medical applications. This low-power logic shifter can be used to buffer, translate, and level shift between different logic families and voltages as well as split and extend bus signals in designs with multiple boards. In communication systems, it can be used for optical transceiver applications requiring interface voltage levels of 1.4V and 3.3V. It can also be used for function control and status signaling between different functional blocks as well as for I/O expansion. In automotive applications, it can be used for multiplexers and output buffer controls as well as for analog-to-digital converters, temperature sensors, and LIN/CAN bus interfaces. In medical applications, the PCA9514DP,118 can be used for level shifting and signal conversion between different system blocks as well as to drive LEDs, Ethernet PHYs and controller applications.

The PCA9514DP,118 operates with two power supplies: one supply is used to drive the inputs while the other is used to switch the output logic level of the channel. The two power supplies must be connected to the PCA9514DP,118 during the active and standby mode to regulate the logic level of the input and output and to ensure correct operation. The PCA9514DP,118 is designed to be operated at frequencies up to 25MHz for reliable operation.

In conclusion, the PCA9514DP,118 is an advanced, low-power logic level translator that is designed tointer faces between different logic families and voltages as well as between TTL and other voltage levels. It is capable of translation, buffering, repeater, and splitting signals for a wide range of applications in communication systems, automotive, and medical systems. The PCA9514DP,118 operates with two power supplies and has a wide operating temperature range, low supply current, extremely low propagation delay, and a low logic 1 level to ensure reliable operation and maximum performance.
