Description

The HD151015 is an IC which consists of 9 bus transceivers (three state output) in a 24 pin package. Signals are transmitter 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. And this product has two terminals (V CCA, VCCB), VCCA is connected with control input and A bus side, VCCB is connected with B bus side. VCCA and VCCB are isolated. Consequently, it is best to change the level in case of two supply voltage coexist on one board and application of power management.

Features

• This product function as level shift transceiver that change VCCA input level to VCCB output level, VCCB input level to VCCA output level by providing different supply voltages to VCCA and VCCB.

• This product is able to the power management : Turn on and off the supply on VCCB side with providing the supply of VCCA. (Enable input (G) : High level)

• Inputs and outputs are CMOS level, and the power dissipation is 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
