ST2149 Datasheet | STMicroelectronics

4-bit dual supply level translator without direction control pin Features - 42 MHz: 84 Mbps (max.) data rate at VL = 1.8 V, VCC = 3.3 V - Bi-directional level translation without direction control pin - Wide voltage range (VCC ≥ VL): - VL ranges from 1.65 to 3.6 V - VCC ranges from VL to 5.5 V - Power-down mode feature - when VCC supply is off, all I/Os are in high impedance - Totem pole driving - 5.5 V tolerant enable pin - ESD performance on all pins: ±2 k V HBM - Small package and footprint QFN16 (2.6 x 1.8 mm) package Applications - Low-voltage system level translation - Mobile phones and other mobile devices Description The ST2149 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. Its architecture allows bi-directional level translation without a control pin. - production data QFN16 (2.6 x 1.8 mm) The ST2149 accepts VL from 1.65 to 3.6 V and VCC from 1.65 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 ST2149 supports power-down mode when VCC is grounded/floating or when the device is disabled via the OE pin.
