DESCRIPTION

· The ST2149 is a 4-bit dual supply level translator designed for multi-voltage system data transfer.

· It supports bidirectional level translation without a control pin.

· Operates with VL from 1.65 to 3.6 V and VCC from 1.65 to 5.5 V.

· Features a tri-state output mode to disable all I/Os.

· Supports power-down mode when VCC is grounded/floating or disabled via the OE pin.

FEATURES

· Data rate up to 84 Mbps at VL = 1.8 V, VCC = 3.3 V.

· Wide voltage range: VL (1.65 to 3.6 V), VCC (1.65 to 5.5 V).

· Power down mode with high impedance I/Os when VCC is off.

· Totem-pole driving.

· 5.5 V tolerant enable pin.

· ESD protection: ±2 kV HBM on all pins.

· Compact QFN16 package (2.6 x 1.8 mm).

APPLICATIONS

· Low voltage system level translation.

· Mobile phones and other mobile devices.
