ST2329I is a 2-bit dual-supply level translator with auto-direction feature and integrated pull-up. It supports wide VL voltage range of 1.65 V to 3.6 V and wide VCC voltage range of 1.80 V to 5.5 V.
The ST2329I is a 2-bit dual-supply level translator designed to allow data transfer in multi-voltage systems. It utilizes a transmission gate based design that enables bidirectional level translation without a control pin, accepting input voltages from 1.65 V to 3.6 V on the VL side and 1.80 V to 5.5 V on the VCC side. The device features integrated 10 kΩ pull-up resistors on both sides and includes a power-down mode where all I/Os enter a high-impedance state when either supply is off.
