HD151015
9 bit Level Shifter/Transceiver With 3 State Outputs
ADE-205-039C (Z)
3rd. Edition
Jun. 1993
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 (VCCA, 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

[Cautions on using]
Please use this IC on condition of VCCA usually ON, because if you use it on condition of VCCA being OFF,
VCCB being ON, it will be troubled.
