1 / 21 page May 2008 Rev 4 1/21 21 ST2329 2-bit dual supply level translator without direction control pin Features ■ 90 Mbps (max) data rate when driven by a totem pole driver ■ 8 Mbps (max) data rate when driven by an open drain pole driver ■ Bidirectional level translation without direction control pin ■ Wide VL voltage range of 1.65 to 3.6 V ■ Wide VCC voltage range of 1.80 to 5.5 V ■ Power down mode feature – when either supply is off, all I/Os are in high impedance ■ Low quiescent current (max 12 µA) ■ Able to be driven by totem pole and open drain drivers ■ 5.5 V tolerant enable pin ■ ESD performance on all pins: ±2 kV HBM ■ Small package and footprint QFN10L (1.8 x 1.4 mm) package Applications ■ Low voltage system level translation ■ Mobile phones and other mobile devices ■ I2C level translation ■ UART level translation Description The ST2329 is a 2-bit dual supply level translator which provides the level shifting capability to allow data transfer in a multi-voltage system. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. It utilizes transmission gate-based design that allows bidirectional level translation without a control pin. The ST2329 accepts a VL from 1.65 to 3.6 V and VCC 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 tri-state output mode which can be used to disable all I/Os. The ST2329 supports power down mode when VCC is grounded/floating and the device is disabled via the OE pin.
