TPT774x

4-Channel Enhanced High-Performance Digital Isolator

Features

Description

The TPT774x devices are high-performance, 4-channel

digital isolators with 5000-V_RMS(WSOP16), and 3750-V_RMS

(SOP16, QSOP16) isolation ratings per UL 1577. These

devices are also to be certified by VDE, UL, CSA, TUV,

CQC, and CB.

150-Mbps Data Rate

•

5-kV RMS Isolation Rating (WSOP)

±200-kV/μs typ Static CMTI, ±150-kV/μs typ Dynamic

CMTI

Low Power Consumption, typ 3 mA/ch @1 Mbps

Low Propagation Delay: 12 ns Typical

•

The TPT774x devices provide high reliability and high

performance at low power consumption with isolating

digital input and output. Each isolation signal channel is

separated by a double capacitive silicon dioxide insulation

barrier. The TPT7740 device has four channels in the

same direction while the TPT7741 device has three

channels in the forward direction and one channel in the

opposite direction. The TPT7742 device has two channels

in the forward direction and two channels in the opposite

direction. In the event of input power or signal loss, the

default output is low for devices with the suffix F and high

for devices without the suffix F.

Default Output Low (TPT774xF) and High (TPT774x)

Wide Temperature Range: −40°C to +125°C

SOP16, QSOP16, and WSOP16 Package

Safety-Related Certifications:

•

VDE Certification according to DIN VDE V

0884-17(IEC60747-17)

–

The common mode transient immunity (CMTI) and

electromagnetic compatibility of the TPT774x devices have

been significantly enhanced through innovative circuit

design and optimized structure.

5000-V_RMS(WSOP16), 3750-V_RMS(SOP16,

QSOP16) Isolation Rating per UL 1577

–

CQC Certification per GB 4943.1

–

The TPT774x family is available in SOP16, QSOP16, and

WSOP16 packages, and is characterized from −40°C to

+125°C.
