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 (V CCA, VCCB), VCCA is connected with control input and A bus side, VCCB is connected with B bus side. VCCA 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 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 85C

Application
For power management system (1)
VCCA system VCCA HD151015
Be able to set up variable power supply voltage from 2 V to 6 V
VCCB system V CCB
Be able to set up variable power supply voltage from 2 V to 6 V Be able to turn on and off
Note:
HD151015 is also used for power management system. We show some Examples. 1. For VCCA side Be able to switch fast mode (V CCA = 5 V) and power save mode (VCCA = 3 V) 2. For VCCB side Be able to switch normal mode (V CCB = 5 V) and suspend mode (VCCB = 0 V) 3. For both side Be able to switch fast mode (V CCA = 5 V) and power save mode (VCCA = 3 V) (When VCCA = VCCB, in this case, please switch V CCA and VCCB simulteneously.)
For power management system (2) (Common bus line in different power system)
VCCA system
VCCB system VCCB = 0 V HD151015 VCCB =0V HD151015 i *1 X *2
"H"
"H" VCCB' system
HD151015 uses conventional CMOS input circuit. So, you have to care of designing in case of common bus line in different power block. We show one example. In this case, if V CCB become turn off, current flows from bus line to V CCB . (refer to *1) This is cause of malfunction. In order to prevent this problem, I recommend using this device for interface to each power block. (refer to * 2)

HD151015
[Cautions on using] Please use this IC on condition of V CCA usually ON, because if you use it on condition of VCCA being OFF, VCCB being ON, it will be troubled.
