ST2129

ST2129 2-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 ■ Bidirectional level translation without direction control pin ■ Wide voltage range (VCC ≥ VL): – VL ranges from 1.65 to 3.6 V – VCC ranges from 1.65 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 kv HBM ■ Small package and footprint: QFN10 (1.8 x 1.4 mm) Applications ■ Low voltage system level translation ■ Mobile phones and other mobile devices QFN10 (1.8 x 1.4 mm) Description The ST2129 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. Its architecture allows bidirectional level translation without a control pin. The ST2129 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 ST2129 supports power-down mode when VCC is grounded/floating or when the device is disabled via the OE pin.
