STMicroelectronics ST2378E
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. For proper operation, VCC should be set higher than VL.| Part No. | ST2378E |

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)
● Low power dissipation – ITS-VL = ITS-VCC = 1 µA (max.) at TA = 85 °C – IQVL = 100 µA (max.) at TA = 85 °C – IQCC = 10 µA (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/O VCC lines
● TSSOP package
DESCRIPTION
Externally applied voltage, VCC and VL, set logic levels at both sides with the range specified as 1.71 V ≤ VL ≤ 5.5 V and VL ≤ VCC ≤ 5.5 V. 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.
