ST2378E 8-bit dual supply 1.71 to 5.5 V level translator with I/O VCC ± 15 KV ESD protection Datasheet − production data Features ■ High speed – tPD = 15 ns (max.) at TA = 85 °C – VL = 1.8 V – VCC = 5.5 V ■ Guaranteed data rate – 13 Mbps (1.8 V ≤ VL ≤ VCC ≤ 5.5 V) ■ Flip-Chip20 Low power dissipation – ITS-VL = ITS-VCC = 1μA (max.) at TA = 85 °C – IQVL = 100 μA (max.) at TA = 85 °C – IQCC = 10μA (max.) at TA = 85 °C ■ Output impedance – |IOHA| = 20 μA (min.) at VL = 1.8 V; VCC = 5.5 V – IOLA = 1.0 μA (min.) at VL = 1.8 V; VCC = 5.5 V ■ Bidirectional level translation ■ Totem pole and open drain driving for I2C communications ■ 5 V tolerant on enable pin ■ Wide operating voltage range – VL (opr.) = 1.71 V to VCC – VCC (opr.) = 1.71 V to 5.5 V ■ ESD performance ■ HBM > 15 KV ESD protection on I/OVCC lines ■ Lead-free Flip-Chip and TSSOP package TSSOP20 Description The ST2378E device is an 8-bit, dual supply, bidirectional level translator with ±15 kV ESD protection on I/Os at VCC side. It is designed to interface data transfer between low voltage ASICs/PLDs and higher voltage systems. Externally applied voltage, VCC and VL, set logic levels at both sides with range specified as 1.71 V ≤ VL ≤ 5.5 V and VL ≤ VCC ≤ 5.5 V. For proper operation, VCC should be set higher than VL. Utilizing a transmission-gate-based design, this device allows bidirectional asynchronous data transfer, which means each channel is allowed to have either VCC to VL or VL to VCC data transfer direction independently and no direction pin is required. The ST2378E device operates at guaranteed data rate of 13 Mbps over the entire specified operating voltage range. Among the other features there is included the OE pin which allows disable mode operation whereby current consumption is reduced to less than 1 µA.
