TS5A63157DBVR

The TS5A63157DBVR is categorized as an Interface device, mainly of the Analog Switches, Multiplexers and Demultiplexers family. This integrated circuit provides high performance, low noise differential signal switching. It contains six single-pole, double-throw (SPDT) switches that can operate from 1.65V to 5.5V.

The TS5A63157DBVR\'s general application fields include sample and hold applications, differential signal routing and medical applications. Moreover, the device has advantages for automotive and industrial applications as it is able to switch large currents of up to 30mA at different supply voltages.

The suggested power supply voltage is from 1.65V to 5.5V, with a maximum possible package combination of a 1.8V supply, divided into two separate 1.4V supplies for true 1.4V operation. This device switches all types of signals, such as single-ended and differential, power and sensitive analogue, by using a low on-resistance of 75Ω and high OFF- isolation of - 90dB at 1MHz. It also supports hot-swapping and hot-insertion, which enables the user to replace and maintain a device in the same network. Some other features of the device include ESD-protection that exceeds 8KV, alongside wide temperature range.

To explain its working principle, the TS5A63157DBVR is controlled through two distinct logic inputs, En_B and En_A, which control the selection and direction of the switches. There are complementary logic inputs. En_B controls channels 1-4 and En_A controls channels 5-6. The logic inputs must be grounded when not in use as the device disables itself when these inputs are left floating.

Moreover, it is inactive when not triggered by the logic. When VDD is below 1.4V, the device is in a low-power sleep mode and does not following the logic inputs. The Enable / Disable pin allows for the entire device to be disabled, regardless of the logic inputs. Additionally, it supports a bidirectional common-mode level translation feature from side A power to side B power, where each side has an individual supply voltage.

A quick explanation of the switch device follows: once powered, the logic pin En_B and En_A will decide which section of the switches should be enabled and which direction the switch should toggle. All the channels except channel 6 don’t have an enable /disable pin and are directly controlled by the logic inputs. The output of each channel is connected to one of the two select pins S1 and S2, while the common pin is connected to a third select pin S3.

The TS5A63157DBVR is designed to work with a wide variety of analogue and digital input conditions, offering high isolation, fast switching speeds and low insertion loss. Thanks to its bidirectional level translator feature, it is also capable of passing signals from one power supply side to the other, making it useful for systems that run at different power supply levels. Additionally, it is well equipped to switch signals in harsh environments due to its 8KV ESD protection level.
