Description

The HD151015 is an IC which consists of 9 bus transceivers (three state output) in a 24 pin package. Signals are transmitted from A to B when the direction control input (DiR) is at a high level, and from B to A when DiR is at a low level. When the enable input (G) is high, A and B are isolated. This product has two terminals (VCCA, VCCB), where VCCA is connected with the control input and A bus side, and VCCB is connected with the B bus side. VCCA and VCCB are isolated, making it ideal for cases where two supply voltages coexist on one board and application of power management is required.

Specifications and features

• Function as a level shift transceiver that changes VCCA input level to VCCB output level, and VCCB input level to VCCA output level by providing different supply voltages to VCCA and VCCB.
• Able to perform power management: Turn on and off the supply on the VCCB side by providing the supply of VCCA. (Enable input (G): High level)
• Inputs and outputs are CMOS level, with power dissipation the same as CMOS standard logic.
• Wide operating supply voltage range: VCCA = VCCB = 2 to 6 V (VCCB V CCA – 0.5 V)
• Wide operating temperature range: Ta = –40 to 85°C

Application Scenarios

This IC is suitable for various electronic applications that require bus transceivers and level shifting. It can be used in systems with different supply voltages, power management requirements, and temperature ranges.
