ST2349A

ST2349A 4-bit dual supply level translator without direction control pin Preliminary Data 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 Bi-directional 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 24 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 QFN16 (2.6 x 1.8 mm) package QFN16L (2.6 x 1.8 mm) Description The ST2349A is a 4-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 bi-directional level translation without a control pin. The ST2349A 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 tristate output mode which can be used to disable all I/Os. The ST2349A supports power down mode when VCC is grounded/floating and the device is disabled via the OE pin. http://www.DataSheet4U.net/ Applications ■ ■ ■ ■ Low voltage system level tra...
