description 1 description the st2329b device is a 2-bit dual supply level translator which provides the level shifting capability to allow data transf er in a multi-voltage system. externally applied voltages, v cc and v l , set the logic levels on either side of th e device. it utilizes a transmission gate-based design that allows bi-directional level translation without a control pin. the st2329b device accepts v l from 1.65 to 3.6 v and v cc from 1.80 to 5.5 v, making it ideal for data transfer between low-voltage asics/pld and higher voltage systems. this device has a tristate output mode wh ich can be used to disable all i/os. the st2329b device supports power-down mode when v cc is grounded/floating and the device is disabled via the oe pin. pin settings st2329b 6/23 docid023359

diagrams 3 device block diagrams figure 2. block diagram 1. when oe is low, all i/o s are in high-impedance mode. 2. the ST2329BQTR has 2 channels. for simplicity, the diagra m above shows only 1 channel. figure 3. application block diagram supplementary notes st2329b 8/23 docid023359 rev 3 4 supplementary notes 4.1 driver requirements the ST2329BQTR may be driven by an open dr ain or totem pole driver and the nature of the device output is ?open drain?. it must not be used to drive a pull-down resistor as the impedance of the output at hi gh state depends on the pull-up resistor placed at the i/os. as the device has pull-up resistors on both the i/o vcc and i/o vl ports, the user needs to ensure that the driver is able to sink the re quired amount of current. for example, if the settings are v cc =5.5v, v l = 4.3 v, and the pull-up resistor is 10 k ? , then the driver must be able to sink at least (5.5 v / 10 k ? ) + (4.3 v / 10 k ? ) ? 1 ma and still meet the v il requirements of the ST2329BQTR. 4.2 load driving capability to support the open drain system, the one-sh ot transistor is turned on only during high transition at the output side. wh en it drives a high state, afte r the one-shot transistor is turned off, only the pull-up resistor is able to maintain the state. in this case, the resistive load is not recommended. 4.3 power-off feature in some applications where it may be required to turn off one of the power supplies powering up the level translator, the user can turn off the v cc only when the oe pin is low (device is disabled). there is no current consumption in v l due to floating gates or other causes, and the i/os are in a high-impedance state in this mode. 4.4 truth table table 3. truth table enable bi-direction al input/output
