Overview
The SN64BCT757DWRE4 is an octal buffer and line driver integrated circuit produced by Texas Instruments. This device is designed to enhance the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. It features BiCMOS design, which significantly reduces the ICCZ (quiescent current) and provides high ESD protection. The device operates over a wide temperature range from –40°C to 85°C and is available in a 20-pin SOIC (Small Outline Integrated Circuit) package.

- High-impedance state during power-up and power-down.
- Open-collector outputs drive bus lines or buffer-memory address registers.
- Complementary output-enable (OE and OE) inputs and noninverting outputs.
- Operating temperature range: –40°C to 85°C.
- Green (RoHS & no Sb/Br) compliant, indicating it is lead-free and free of bromine and antimony based flame retardants.
Applications
- 3-state memory address drivers.
- Clock drivers.
- Bus-oriented receivers and transmitters.
- General-purpose buffering and driving applications where high impedance during power-up and power-down is required.
