ST2378ETTR

ST2378ETTR is an 8bit, dual supply, bidirectional level translator with ±15KV 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 the range specified as 1.71V = VL = 5.5V and VL = VCC = 5.5V. 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 a guaranteed data rate of 13Mbps over the entire specified operating voltage range.

• High speed: tPD = 15ns (max.) at TA = 85 °C, VL = 1.8V, VCC = 5.5 V
• Guaranteed data rate of 13Mbps (1.8 V = VL = VCC = 5.5V)
• Low power dissipation: ITS-VL = ITS-VCC = 1µA (max.) at TA = 85°C
• Output impedance: (IOHA) = 20µA (min) at VL = 1.8V; VCC = 5.5V
• Bidirectional level translation
• Totem pole and open drain driving for I2C communications
• 5V tolerant on enable pin
• ESD performance
• HBM 15KV ESD protection on I/O VCC lines
• 20 lead TSSOP package, temperature range from -40°C to +85°C
