The SN64BCT757DWG4 is a quad bidirectional translator and voltage-level shifter designed to translate logic levels between any of five popular logic families; namely, LVTTL, LVCMOS, HSTL, SSTL2 and SSTL3. These devices allow communication between different logic families without generation of signals outside of the supply rails of the receiving logic family. The SN64BCT757DWG4 has four bidirectional translation channels, each consisting of one logic driver and one logic receiver.

The SN64BCT757DWG4 is used in applications such as memory expansion and protocol conversion. It is capable of providing clean, low-skew, high-speed switching for high-performance systems. It is also well suited for applications where multiple levels of I/O voltages are needed and for systems where two or more voltage levels are used for the different I/O standards.

The SN64BCT757DWG4 operates from a single 3.3 V supply. Each channel has its own supply current, which is determined by the number of channels that are enabled. The device is specified over an operating temperature range of -40 ˚C to 85 ˚C and is available in an 8-pin TSSOP package.

The working principle of the SN64BCT757DWG4 is based on a charge coupled architecture. It has four bidirectional channels – one for each of the five different logic levels (LVTTL, LVCMOS, HSTL, SSTL2, and SSTL3). Each of the channels consists of one logic driver and one logic receiver. The device is designed to translate logic levels between any of the five logic families.

The device utilizes a charge-coupled shift register architecture to achieve the level translations. This architecture works by using a combination of C-Mos and BiCMOS components to accomplish the level shifting. The charge-couple architecture removes the need for additional level-shifters, which can be expensive and complex to implement. In addition, the device features programmable slew rate, output drive strength, equalization and glitch-free logic levels.

The SN64BCT757DWG4 is a versatile and powerful logic translator and voltage-level shifter. It is capable of providing clean, low-skew, high-speed switching for high-performance systems, and is well suited for applications where multiple levels of I/O voltages are needed and for systems where two or more voltage levels are used for the different I/O standards. It operates from a single 3.3 V supply and is specified over an operating temperature range of -40 ˚C to 85 ˚C.
