Nexperia USA Inc. 74LVC1G79GN,132

Overview

74LVC1G79GN,132 from Nexperia is a single positive-edge-triggered D-type flip-flop in an XSON6 package (SOT1115), operating from 1.65 V to 5.5 V supply. It stores data at the D-input on LOW-to-HIGH clock transitions, features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, and supports mixed-voltage interfacing between 3.3 V and 5 V systems - used in clock-synchronized data latching in compact industrial controllers.

For engineers reviewing the 74LVC1G79GN,132 datasheet, 74LVC1G79GN,132 pinout, 74LVC1G79GN,132 application, or 74LVC1G79GN,132 equivalent, key selection criteria include its 6-terminal XSON6 footprint (0.9 × 1.0 × 0.35 mm), ±24 mA output drive at 3.0 V, 5.0 ns max propagation delay at 3.3 V, and guaranteed operation from –40 °C to +125 °C.

Technical Context

This device implements a synchronous edge-triggered storage element with transparent input behavior only during the active clock edge. Its Schmitt-trigger inputs accept slow-rising signals without oscillation, and the IOFF circuit disables outputs when VCC = 0 V to prevent backflow current in partial-power-down systems.

The logic function follows standard D-flip-flop behavior: Q output updates to match D input only on the rising edge of CP, with setup time as low as 0.6 ns and hold time as low as –0.3 ns at 3.3 V, enabling reliable timing in high-speed digital interfaces up to 450 MHz.

FAQ

What is the maximum clock frequency supported by the 74LVC1G79GN,132?

The 74LVC1G79GN,132 supports up to 450 MHz maximum clock frequency at VCC = 3.3 V and Tamb = –40 °C to +85 °C, and 400 MHz at full –40 °C to +125 °C range. This is verified per Table 8 dynamic characteristics with CL = 50 pF and RL = 500 Ω test conditions.

Can the 74LVC1G79GN,132 safely interface between 5 V and 3.3 V logic domains?

Yes - its inputs tolerate up to 5.5 V regardless of VCC level (1.65 V to 5.5 V), and outputs swing rail-to-rail. When powered at 3.3 V, it accepts 5 V inputs without damage and drives 3.3 V-compatible loads, enabling true bidirectional voltage translation without external components.

Is Pin 5 (n.c.) required to be left floating, or can it be grounded?

Pin 5 is internally unconnected and must remain floating - neither grounded nor tied to VCC. Connecting it risks unintended parasitic coupling or package stress; Nexperia's datasheet explicitly defines it as "not connected" with no internal bond wire or circuit attachment.

Does the 74LVC1G79GN,132 support hot-swap or partial power-down operation?

Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting power-off leakage to ±2 μA max and blocking backflow current. This enables safe insertion/removal in live backplanes and controlled power sequencing in multi-rail systems per JEDEC JESD78 compliance.
