Texas Instruments SN74AUP1G80YZPR

Overview

SN74AUP1G80YZPR from Texas Instruments is a single positive-edge-triggered D-type flip-flop in a 5-pin DSBGA package (0.89 mm × 1.39 mm), operating across 0.8 V to 3.6 V supply voltage, with 4.4 ns maximum propagation delay at 3.3 V and 0.9 µA maximum ICC. It supports partial-power-down via Ioff and features Schmitt-trigger inputs (250 mV typical hysteresis) for noise immunity in low-voltage portable timing circuits.

For engineers reviewing the SN74AUP1G80YZPR datasheet, SN74AUP1G80YZPR pinout, SN74AUP1G80YZPR application, or SN74AUP1G80YZPR equivalent, key selection criteria include its ultra-low static/dynamic power (ICC ≤ 0.9 µA, Cpd = 4.3 pF), 3.6-V I/O tolerance for mixed-mode interfacing, and validated operation from –40°C to +85°C in space-constrained battery-powered systems.

Technical Context

The SN74AUP1G80YZPR implements a synchronous edge-triggered storage element with data transfer on the rising clock edge only when setup/hold timing is met. Its balanced CMOS push-pull output drives ±4 mA at 3 V while maintaining low overshoot/undershoot (<10% of VCC).

It integrates Ioff circuitry that disables outputs during power-down to prevent backflow current, and Schmitt-trigger action on both D and CLK inputs enables robust operation with slow or noisy signals-critical for industrial control and sensor interface applications where signal integrity cannot be assumed.

FAQ

What is the minimum supply voltage required for guaranteed operation of the SN74AUP1G80YZPR?

The SN74AUP1G80YZPR is fully specified from 0.8 V to 3.6 V. At 0.8 V, it supports up to 20 MHz clock frequency with 5.5 ns minimum pulse width and meets all AC/DC specifications across –40°C to +85°C. This enables direct use with single-cell Li-ion or NiMH batteries without regulation.

Does the SN74AUP1G80YZPR support partial power-down, and how does it behave when VCC = 0 V?

Yes, the SN74AUP1G80YZPR implements Ioff circuitry. When VCC = 0 V, all inputs and outputs enter high-impedance states with leakage ≤0.6 µA, preventing current backflow into powered sections of the system. This protects the device and adjacent circuitry during hot-swap or multi-rail sequencing events.

Can the SN74AUP1G80YZPR be used as a frequency divider, and what design considerations apply?

Yes-the SN74AUP1G80YZPR can implement a 2× frequency divider by connecting Q to D. A series resistor (e.g., 10 kΩ) on the feedback path is required to allow override initialization. The device has no preset/clear, so initial Q state is undefined; external reset logic or an override pin must set the starting condition before enabling CLK.

What is the significance of Schmitt-trigger inputs on the SN74AUP1G80YZPR, and how does it affect system design?

The Schmitt-trigger inputs on SN74AUP1G80YZPR provide 250 mV typical hysteresis at 3.3 V, allowing reliable operation with slow or noisy signals (e.g., from mechanical switches or long traces). This eliminates need for external RC filters or dedicated Schmitt buffers, reducing BOM count and PCB area in industrial and consumer interfaces.

Is the SN74AUP1G80YZPR pin-compatible with other members of the AUP family, such as SN74AUP1G74 or SN74AUP1G79?

No-SN74AUP1G80YZPR is a single D-type flip-flop with D, CLK, Q, VCC, and GND pins. SN74AUP1G74 is a dual DFF in 6-pin packages (e.g., YFP/DSF), and SN74AUP1G79 is a D-latch. Pinouts differ fundamentally: SN74AUP1G80YZPR has no enable or clear pins, and its 5-ball DSBGA layout is unique to this variant. Board redesign is required for substitution.
