SN74LVC1T45DCKR, an small-outline package dual bus bidirectional translator, is classified as a Logic-Translators, Level shifters. This dual-channel logic device integrates two independent level translation channels with latch-based output enables. This device is designed to be used in systems that operate with power-supply voltage range of 1.65V to 5.5V. It is an ideal solution for designs with multiple compatible power domains, and it is also suitable for low-voltage and low-power applications.
The SN74LVC1T45DCKR consists of two bidirectional A and B channels, each possessing four configurable input/output terminals and two active-low latch-enable (LEA, LEB) terminals. The A and B channels are configured by two select inputs (SELA, SELB), two active-low latch-enable (LEA, LEB) and two active-high latch-enable (HEA, HEB) terminals. The select inputs and latch-enable inputs are used to control the level translation between VCCA and VCCB power domains. The select inputs, LEA and LEB, can be used to control the level-shifting direction between the two power domains.
In addition to its dual channel capability, the SN74LVC1T45DCKR also supports a low-voltage operation with a VCCA voltage range of 1.65V to 3.6V and a VCCB voltage range of 1.2V to 5.5V. This feature ensures that the device can be used in low voltage and low-power applications. It also supports a wide variery of transmission interface protocols such as I2C, SPI, UART and USB. The device is also capable of providing an asynchronous reset capability through the active-low reset terminal. This feature is used to reset the output states of the device.
The working principle of the SN74LVC1T45DCKR is dependent on its input/output terminals and its level translation capability. The device typically operates in one of two modes, “Level translation only” or “Latching Output Enable”. In level translation mode, the level of the B port signals are translated to that of the A port. This is done by toggling the select signals of the respective channels and setting the latch-enable inputs into the appropriate state. In “Latching Output Enable” mode, the device will latch the outputs of the A port when the latch-enable inputs are enabled. This mode is useful for applications that require the device to latch the output states of the bus or interface signals that it is connected to.
The SN74LVC1T45DCKR is an ideal device for use in high-speed system designs where the power between two devices or systems needs to be monitored and translated. It is suitable for designs with multiple compatible power domains and can be used in applications such as power supply monitoring, data bus translation, bus bridging and voltage level shifting. As it operates with a wide variety of input/output signals, it can also be used as a signal conditioning module in a variety of communication interface applications such as USB, UART and I2C.
The SN74LVC1T45DCKR is a versatile and compact logic device which provides level translation between two power domains. It is suitable for low-voltage and low-power applications and supports a wide variety of transmission protocols. It can be used as a signal conditioning module in different types of communication interfaces as well as for powering supply monitoring, data bus translation and bus bridging.
