Texas Instruments SN74LVC1G80YEAR

Overview

SN74LVC1G80YEAR from Texas Instruments is a single positive-edge-triggered D-type flip-flop designed for 1.65V to 5.5V V_CC operation, delivering 4.2ns maximum propagation delay at 3.3V, ±24mA output drive, and I_off support for partial-power-down mode - used in clock frequency division, data synchronization, and edge-sensitive control logic within enterprise switching and telecom infrastructure.

For engineers reviewing the SN74LVC1G80YEAR datasheet, SN74LVC1G80YEAR pinout, SN74LVC1G80YEAR application, or SN74LVC1G80YEAR equivalent, key selection criteria include its 5-pin DSBGA (YZP) package, 1.3ns minimum setup time at 3.3V, 0.9ns hold time, 160MHz max clock frequency, and over-voltage tolerant inputs up to 5.5V independent of V_CC.

Technical Context

The SN74LVC1G80YEAR implements a CMOS-based positive-edge-triggered D flip-flop with transmission-gate logic architecture. Its clock triggering occurs at a defined voltage threshold-not dependent on input slew rate-enabling robust timing behavior across varying signal rise times.

It features balanced push-pull outputs capable of sourcing/sinking ±24mA at 3.3V, standard CMOS inputs with 3.5pF typical input capacitance, and integrated clamp diodes supporting ±2000V HBM ESD protection. The I_off circuitry ensures high-impedance outputs during power-down, preventing back-drive current flow.

FAQ

What is the maximum clock frequency supported by SN74LVC1G80YEAR?

The SN74LVC1G80YEAR supports a maximum clock frequency of 160MHz across its full operating temperature range (–40°C to +125°C) when V_CC ≥ 1.8V and load capacitance ≤ 15pF. At 3.3V and CL = 15pF, it achieves this rating with 1.3ns setup time and 4.2ns propagation delay - verified per TI's SCES221T datasheet Section 5.6 and 5.7.

Does SN74LVC1G80YEAR support 5V input signals while operating at 1.8V V_CC?

Yes, SN74LVC1G80YEAR supports input voltages up to 5.5V on D and CLK pins regardless of V_CC level - including operation at 1.8V. This over-voltage tolerance is explicitly specified in Section 5.3 (Recommended Operating Conditions) and Section 5.1 (Absolute Maximum Ratings) of the official datasheet, eliminating need for external level shifters.

What is the purpose of the I_off feature in SN74LVC1G80YEAR?

The I_off feature in SN74LVC1G80YEAR disables all outputs and places them in high-impedance state when V_CC = 0V, limiting leakage current to ±10µA. This prevents back-drive current from other powered sections of the system - critical for hot-swap, partial-power-down, and safe power sequencing in modular electronics designs.

Which package does SN74LVC1G80YEAR use, and what are its dimensions?

SN74LVC1G80YEAR uses the YZP package - a 5-pin DSBGA (Die Size Ball Grid Array) measuring 1.41mm × 0.91mm with 0.4mm ball pitch. As confirmed in TI's SCES221T datasheet Section 11 and Package Information table, this NanoFree™ implementation uses the silicon die itself as the package substrate for minimal thickness and parasitic inductance.

Can SN74LVC1G80YEAR be used as a divide-by-two frequency divider?

Yes, SN74LVC1G80YEAR can implement a reliable divide-by-two function by connecting Q to D and applying the input clock to CLK. As documented in Section 8.1 of the datasheet, this toggle-mode configuration produces a 50% duty-cycle output with deterministic phase alignment - though initial state is undefined and may require GPIO initialization in production firmware.
