1. General description

The NTS0101 is a 1-bit, dual supply translating transceiver with auto direction sensing,

that enables bidirectional voltage level translation. It features two 1-bit input-output ports

(A and B), one output enable input (OE) and two supply pins (V

CC(A)

and V

CC(B)

). V

CC(A)

can be supplied at any voltage between 1.65 V and 3.6 V. V

CC(B)

can be supplied at any

voltage between 2.3 V and 5.5 V. This flexibility makes the device suitable for translating

between any of the voltage nodes (1.8 V, 2.5 V, 3.3 V and 5.0 V). Pins A and OE are

referenced to V

CC(A)

and pin B is referenced to V

CC(B)

. A LOW level at pin OE causes the

outputs to assume a high-impedance OFF-state. This device is fully specified for partial

power-down applications using I

OFF

. The I

OFF

circuitry disables the output, preventing the

damaging backflow current through the device when it is powered down.

The NTS0101 can be used in point-to-point applications to interface between devices or systems operating at different supply voltages. The device is primarily targeted at I2C or 1-wire which use open-drain drivers.
PAGE 14
NTS0101 NXP Semiconductors Dual supply translating transceiver; open drain; auto direction sensing The gate bias voltage of the pass gate transistor (T3) is set at approximately one threshold voltage above the VCC level of the low-voltage side. During a LOW-to-HIGH transition, the output one-shot accelerates the output transition by switching on the PMOS transistors (T1, T2). It bypasses the 10 k pull-up resistors and increases the current drive capability.

NTS0101 NXP Semiconductors Dual supply translating transceiver; open drain; auto direction sensing 14.7 Pull-up or pull-down resistors on I/Os lines The A port I/O has an internal 10 k pull-up resistor to VCC(A). The B port I/O has an internal 10 k pull-up resistor to VCC(B). If a smaller value of pull-up resistor is required, add an external resistor in parallel to the internal 10 k. This pull-up resistor effects the VOL level. When OE goes LOW, the internal pull-ups of the NTS0101 are disabled.
