Product details
Overview
74AHC1G79GW,165 from Nexperia is a single positive-edge-triggered D-type flip-flop in TSSOP5 (SOT353-1) package, operating from 2.0 V to 5.5 V supply. It stores data on the LOW-to-HIGH clock transition with 3.0 ns minimum set-up time and 8.0 ns typical propagation delay at 3.3 V/15 pF. Designed for level translation in mixed-voltage systems, it supports industrial temperature range (−40 °C to +125 °C) and features overvoltage-tolerant inputs up to 5.5 V.
For engineers reviewing the 74AHC1G79GW,165 datasheet, 74AHC1G79GW,165 pinout, 74AHC1G79GW,165 application, or 74AHC1G79GW,165 equivalent, this device serves as a compact, low-power edge-triggered storage element for timing-critical digital logic, voltage-level interfacing, and synchronous control in space-constrained PCBs.
Technical Context
This flip-flop implements a synchronous positive-edge-triggered D latch function with CMOS input thresholds. Its internal structure includes Schmitt-trigger-free inputs, symmetrical output drivers, and balanced propagation delays between Q and Q̅ paths - enabling precise edge-aligned sampling in clock domain crossing and state-holding circuits.
The device operates across a wide VCC range (2.0–5.5 V) while maintaining TTL-compatible input thresholds only in the AHCT variant; the AHC version uses true CMOS thresholds. Input overvoltage tolerance (up to 5.5 V independent of VCC) enables safe interfacing between 3.3 V logic and 5 V peripherals without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Type | Single D-type flip-flop, positive-edge triggered - stores one bit on rising clock edge |
| Supply Voltage Range | 2.0 V to 5.5 V - supports dual-rail 3.3 V and 5 V systems without voltage translation |
| Propagation Delay (tpd) | 4.9 ns typ @ 3.3 V, 15 pF - enables reliable operation up to 90 MHz maximum clock frequency |
| Set-up Time (tsu) | 3.0 ns min @ 25 °C - defines minimum D-input stability window before clock edge for valid capture |
| Input Voltage Tolerance | −0.5 V to +7.0 V - allows safe connection to higher-voltage signals without damage or clamping diodes |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood, industrial control, and power-conversion applications |

Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | D | Data input - sampled on rising CP edge; overvoltage tolerant to 5.5 V |
| 2 | CP | Clock pulse input - positive-edge sensitive; VIH = 3.85 V min @ VCC = 5.5 V |
| 3 | GND | Ground reference - return path for all internal currents and I/O |
| 4 | Q | True data output - CMOS rail-to-rail swing; VOH ≥ 3.94 V @ IO = −8 mA, VCC = 4.5 V |
| 5 | VCC | Supply voltage - powers internal logic and output drivers; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 2.0 V to 5.5 V operation enables direct use in 3.3 V and 5 V domains without regulators |
| Overvoltage-tolerant inputs | Inputs withstand up to 5.5 V regardless of VCC - eliminates need for external clamping in mixed-voltage interfaces |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduced signal distortion |
| High noise immunity | CMOS input thresholds and 0.1 V typical VOL/VOH margins suppress false triggering in noisy environments |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G79GW,165 | TTL-compatible input thresholds (VIH = 2.0 V min), otherwise identical pinout, timing, and package | Required when interfacing with legacy 5 V TTL outputs; AHC variant unsuitable due to higher VIH | Select AHCT if driving from standard 5 V TTL sources; AHC preferred for pure CMOS systems with 3.3 V signaling |
| SN74LVC1G79DBVR | Lower VCC range (1.65–5.5 V), 3.3 ns tpd @ 3.3 V, but no overvoltage-tolerant inputs (max VI = VCC + 0.3 V) | Not suitable for mixed-voltage translation; requires strict voltage alignment between driver and receiver | Choose only in fully 3.3 V systems where board-level voltage coordination is guaranteed and overvoltage risk is absent |
Compared with 74AHCT1G79GW,165, the AHC variant offers superior noise margin in CMOS environments but lacks TTL compatibility; versus SN74LVC1G79DBVR, it trades slightly higher propagation delay for robust 5.5 V input tolerance - critical in unregulated or multi-supply designs.

FAQ
What is the maximum clock frequency supported by the 74AHC1G79GW,165?
The device supports up to 90 MHz maximum clock frequency at 25 °C and VCC = 3.0–5.5 V with CL = 15 pF. At full temperature range (−40 °C to +125 °C), fmax derates to 70 MHz due to increased propagation delay and reduced drive strength at temperature extremes.
Can the 74AHC1G79GW,165 be used to interface a 5 V microcontroller GPIO with a 3.3 V FPGA input?
Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC, allowing direct connection of 5 V logic outputs to the D or CP pins while powered from 3.3 V. No external level shifter is needed, provided output drive strength meets 4 mA sink/source requirements.
Does the 74AHC1G79GW,165 have a reset or clear function?
No - this is a basic single D-type flip-flop with only D, CP, Q, VCC, and GND terminals. It lacks asynchronous reset (CLR) or preset (PRE) inputs. For resettable operation, consider the 74AHC1G80 (D-type with asynchronous reset) or discrete gating of the D input.
Is the TSSOP5 package (SOT353-1) compatible with standard reflow profiles?
Yes - the SOT353-1 package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. Its 0.65 mm pitch and thermal mass allow reliable soldering using standard Type 3 or Type 4 solder paste and industry-standard profile ramp-soak-reflow cycles.
