SN75976A1DLR Description

Short technical summary and product information.

The SN75976A1DLR is a 9-channel differential transceiver manufactured by Texas Instruments, suitable for applications requiring RS422 and RS485 interfaces. This device is designed to operate within a voltage range of 4.75V to 5.25V, with a typical operating temperature range of 0°C to 70°C.

 

It features nine differential channels for data and control paths, supporting half-duplex communication. The transceiver offers improved switching performance and ESD protection exceeding 12 kV on bus terminals. It is designed to operate at data transfer rates up to 20 million transfers per second, making it suitable for high-speed parallel data buses like Fast-20 SCSI.

 

The SN75976A1DLR is supplied in a 56-SSOP package, specifically a 56-BSSOP with a 7.50mm width. This surface-mount package is a Thin Shrink Small-Outline Package (TSSOP), offering reduced board area requirements and a low profile.

 

Key electrical characteristics include a receiver hysteresis of 45 mV and a low disabled supply current of 8 mA typical. The device also incorporates thermal shutdown protection and positive/negative current limiting for enhanced reliability.
