ST2329I Datasheet, PDF (1/22 Pages) STMicroelectronics – 2-bit dual-supply level translator with auto-direction feature and integrated pull-up

ST2329I
2-bit dual-supply level translator with auto-direction feature
and integrated pull-up
Target specification
Features
■ 18 Mbps (max.) data rate when driven by
a totem pole driver
■ 6.8 Mbps (max.) data rate when driven by
an open drain pole driver
■ Bidirectional level translation, without direction
pin
■ Wide V_L voltage range of 1.65 V to 3.6 V
■ Wide V_CC voltage range of 1.80 V to 5.5 V
■ Integrated 10 kΩ pull-up on both V_CC and V_L
sides
■ Power-down mode feature; when either supply
is off, all I/Os are in high impedance
■ Low quiescent current (max. 4 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 - QFN10
(1.8 x 1.4 mm) package
