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, V_CCB), V_CCA is connected with control input and A bus side, V_CCB is connected
with B bus side. V_CCA and V_CCB 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 V_CCA input level to V_CCB output level, V_CCB
input level to VCCA output level by providing different supply voltages to V_CCA and V_CCB.
• This product is able to the power management : Turn on and off the supply on V_CCB side with providing
the supply of V_CCA.
(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:
V_CCA = V_CCB = 2 to 6 V (V_CCB V _CCA – 0.5 V)
• Wide operating temperature range: Ta = –40 to 85°C
