Texas Instruments SN74AUP1T98DBVR

Overview

SN74AUP1T98DBVR from Texas Instruments is a single-supply voltage-level translator IC with configurable logic functions, operating from 2.3 V to 3.6 V VCC, supporting 1.8 V/2.5 V/3.3 V bidirectional level translation, featuring Schmitt-trigger inputs (ΔVT = 0.25 V min), Ioff protection (0.5 μA), and 4 mA output drive - used in mixed-voltage I²C, GPIO, and power-aware sensor interface circuits.

For engineers reviewing the SN74AUP1T98DBVR datasheet, SN74AUP1T98DBVR pinout, SN74AUP1T98DBVR application, or SN74AUP1T98DBVR equivalent, key selection criteria include its 6-pin SOT-23 package, nine programmable logic configurations via A/B/C input biasing, ultra-low static current (0.9 μA max), hysteresis-enhanced noise immunity, and compatibility with battery-backed systems requiring partial-power-down operation.

Technical Context

The SN74AUP1T98DBVR implements a single-output, three-input configurable gate using AUP ultra-low-power CMOS technology. Its Schmitt-trigger inputs provide 210 mV hysteresis (VT+ − VT−) across 2.3–3.6 V VCC, enabling robust switching in noisy analog-digital boundary environments. The device accepts input voltages up to 3.6 V independent of VCC and supports Ioff when VCC = 0 V.

Logic configuration is determined by hard-wiring inputs A, B, and C to VCC or GND per the Function Selection Table - enabling 2-to-1 data selection, NAND/NOR variants, inverter, and buffer functions without external programming. Propagation delay ranges from 1.6 ns (CL = 5 pF, VCC = 3.3 V, VI = 1.8 V) to 10.8 ns (CL = 30 pF, VCC = 2.5 V, VI = 1.8 V).

FAQ

What logic functions can the SN74AUP1T98DBVR implement?

The SN74AUP1T98DBVR supports nine configurable logic functions including 2-to-1 data selector, 2-input NAND/NOR gates (standard and with one inverted input), inverter, and noninverted buffer. Configuration is achieved by connecting inputs A, B, and C to VCC or GND per the Function Selection Table in the datasheet - no external programming or configuration registers are required. Each function is implemented in hardware based on static biasing.

Does the SN74AUP1T98DBVR require external pull-up resistors?

No, the SN74AUP1T98DBVR does not require external pull-up resistors for normal operation. Its CMOS push-pull output drives rail-to-rail and sources/sinks up to ±4 mA. Pull-ups are only needed if implementing open-drain emulation (e.g., for I²C), which is not a native function of the SN74AUP1T98DBVR - alternative devices like TXS0102 are better suited for that purpose.

Can the SN74AUP1T98DBVR translate between 1.2 V and 3.3 V logic levels?

No, the SN74AUP1T98DBVR does not support 1.2 V input translation. Its input thresholds are specified for 1.8 V, 2.5 V, and 3.3 V systems (VIH min = 1.10 V at VCC = 2.5 V; 1.19 V at VCC = 3.3 V). A 1.2 V input falls below the guaranteed VIH and may result in indeterminate output states. For 1.2 V interfaces, consider TI's SN74AXP1T245 or similar dedicated low-VTH translators.

What is the maximum capacitive load the SN74AUP1T98DBVR can drive reliably?

The SN74AUP1T98DBVR is characterized up to 30 pF load capacitance in switching specifications, with tpd increasing from 1.6 ns (5 pF) to 10.8 ns (30 pF) depending on VCC and input voltage. Driving >30 pF may cause timing violations or increased rise/fall times. For heavier loads, add a series resistor to dampen ringing or use a higher-drive buffer such as SN74AUP2G04.

Is the SN74AUP1T98DBVR pin-compatible with other members of the SN74AUP1Txx family?

Yes, the SN74AUP1T98DBVR shares the same SOT-23-6 (DBV) footprint and pinout with SN74AUP1T97DBVR, SN74AUP1T57DBVR, and SN74AUP1T58DBVR - all have identical pin assignments (A, B, GND, C, Y, VCC). This allows drop-in replacement for different logic functions within the same board layout, provided the application-specific function matches the truth table of the substituted device.
