Texas Instruments TCA9517DR Specialized Interface I2C Smbus Bus & Systems Applications Servers Telecom 900 mV
Texas Instruments TCA9517DR Specialized Interface I2C Smbus Bus & Systems Applications Servers Telecom 900 mV
The TCA9517DR is a bidirectional Buffer with level shifting capabilities for I²C and SMBus systems. It provides bidirectional voltage-level translation (up-translation/down-translation) between low voltages and higher voltages (2.7 to 5.5V) in mixed-mode applications. This device enables I²C and SMBus systems to be extended without degradation of performance, even during level shifting. The TCA9517 buffers both the serial data and the serial clock signals on the I²C bus, thus allowing two buses of up to 400pF bus capacitance to be connected in an I²C application. It has two types of drivers: A-side drivers and B-side drivers. All inputs and I/Os are over-voltage tolerant to 5.5 V, even when the device is unpowered (VCCB and/or VCCA = 0 V). The type of buffer design on the B-side prevents it from being used in series with devices which use static voltage offset.
- I²C Bus and SMBus Compatible
- Footprint and functional replacement for PCA9515B
- Active-high repeater-enable input
- Open-drain I²C I/O
- 5.5V Tolerant I²C and enable input support mixed-mode signal operation
- Accommodates standard-mode and fast-mode I²C devices and multiple masters
- High-impedance I²C pins when powered-off
- Latch-up performance exceeds 100 mA per JESD 78, class II
- ESD Protection exceeds JESD 22
- Green product and no Sb/Br
Industrial, Communications & Networking
Warnings Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.Other details
