Voltage Level Translator Bidirectional 1 Circuit 8 Channel 60Mbps 20-TSSOP This device is an 8-bit non-inverting level translator which uses two separate configurable power-supply rails. The A port tracks the VCCA pin supply voltage. The VCCA pin accepts any supply voltage between 1.4V and 3.6V. The B port tracks the VCCB pin supply voltage. The VCCB pin accepts any supply voltage between 1.65V and 5.5V. Two input supply pins allows for low Voltage bidirectional translation between any of the 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. When the output-enable (OE) input is low, all outputs are placed in the high-impedance (Hi-Z) state. To put the device in the Hi-Z state during power-up or power-down periods, tie OE to GND through a pulldown resistor. The current-sourcing capability of the driver determines the minimum value of the resistor. • No direction-control signal needed • Maximum data rates: – 110Mbps (push pull) – 1.2Mbps (open drain) • 1.4V to 3.6V on A port and 1.65V to 5.5V on B port (VCCA ≤ VCCB) • No power-supply sequencing required – either VCCA or VCCB can be ramped first • Latch-up performance exceeds 100mA per JESD 78, class II • ESD protection exceeds JESD 22 (A port): – 2000 V Human Body Model (A114-B) – 150 V Machine Model (A115-A) – 1000 V Charged-Device Model (C101) • IEC 61000-4-2 ESD (B-port): – ± 8kV Contact Discharge – ± 6kV Air Discharge #commonpartslibrary #integratedcircuit #logic #translator #levelshifter

Precision 24-bit analog-to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. Based on Avia Semiconductor’s patented technology, HX711 is a precision 24-bit analogto-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input voltage of ±20mV or ±40mV respectively, when a 5V supply is connected to AVDD analog power supply pin. Channel B has a fixed gain of 32. Onchip power supply regulator eliminates the need for an external supply regulator to provide analog power for the ADC and the sensor. Clock input is flexible. It can be from an external clock source, a crystal, or the on-chip oscillator that does not require any external component. On-chip poweron-reset circuitry simplifies digital interface initialization. There is no programming needed for the internal registers.
