Product details
Overview
74AVC16722DGGRE4 from Texas Instruments is a 22-bit edge-triggered D-type flip-flop with 3-state outputs, Dynamic Output Control (DOC) circuitry, ±24 mA dynamic drive at 2.5 V, 1.2–3.6 V supply range, and -40°C to 85°C operation-used in high-speed bus interface and data synchronization in multi-voltage systems.
For engineers reviewing the 74AVC16722DGGRE4 datasheet, 74AVC16722DGGRE4 pinout, 74AVC16722DGGRE4 application, or 74AVC16722DGGRE4 equivalent, this page delivers verified electrical specs, DOC noise-reduction behavior, Ioff partial-power-down support, TSSOP-64 package mapping, and real-world timing performance across 1.2–3.3 V rails.
Technical Context
The 74AVC16722DGGRE4 implements EPIC submicron CMOS process and DOC circuitry that dynamically lowers output impedance during signal transition for fast edge drive, then raises it to suppress switching noise-enabling 175 MHz max clock frequency at 3.3 V without speed penalty. Its dual control inputs (CLKEN and OE) operate independently: CLKEN gates clock propagation to internal flip-flops, while OE places all 22 outputs in high-impedance state without affecting stored data.
Designed for mixed-voltage-mode communication, the device features overvoltage-tolerant I/Os (–0.5 V to 4.6 V), Ioff protection for partial-power-down, and latch-up immunity exceeding 100 mA per JESD 78 Class I. Input thresholds scale with VCC (e.g., VIH = 0.65×VCC for 1.65–1.95 V), ensuring robust interfacing across 1.2–3.6 V domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 22-bit positive-edge-triggered D-type flip-flop with independent clock-enable and 3-state output control |
| Supply Voltage Range | 1.2 V to 3.6 V; fully specified for 1.65–3.6 V operation with scalable input thresholds |
| Max Clock Frequency | 175 MHz at VCC = 3.3 V - enables high-throughput data latching in DDR and parallel bus applications |
| Dynamic Drive Strength | ±24 mA at 2.5 V - matches standard-output drive without added noise or delay penalty due to DOC architecture |
| Propagation Delay (tpd) | 2.6 ns typical at VCC = 3.3 V - supports sub-4 ns timing margins in high-speed synchronous designs |
| Ioff Support | Enables safe partial-power-down mode by disabling outputs and blocking reverse current flow when VCC = 0 V |

Pinout & Package
Packaged in 64-pin Thin Shrink Small-Outline Package (TSSOP-DGG), 12.6 mm × 6.2 mm body, 0.5 mm pitch, JEDEC MO-153 compliant, with exposed pad not present and moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock input | Positive-edge-triggered master clock for all 22 flip-flops; timing-critical path with 2.6 ns tpd at 3.3 V |
| CLKEN | Clock enable input | Asynchronous gate for clock propagation; low enables storage on CLK↑, high blocks updates regardless of CLK |
| OE | Output enable input | Active-low 3-state control; high-Z outputs retain bus integrity without affecting internal Q-state or CLKEN functionality |

| VCC / GND | Power terminals | Four VCC and five GND pins distributed across package for low-noise power delivery and reduced ground bounce |
| NC | No-connect terminal | Pin 33 is unconnected internally; must be left floating or tied to GND/VCC per layout best practice |
Key Features

|---|---|
| Dynamic Output Control (DOC) | Reduces simultaneous switching noise by modulating output impedance mid-transition while maintaining 175 MHz clock rate |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 22-bit registered buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16722DGGR | Same die, identical specs, RoHS-compliant NiPdAu lead finish; differs only in tape-and-reel packaging (no E4 suffix) | No functional difference; suitable for same PCBs and thermal profiles | Select DGGR for standard production runs where E4 marking is not required for traceability |
| SN74LVC16374DGGR | 22-bit LVC-family flip-flop; no DOC circuitry, lower drive (±24 mA only at 3.3 V), VIH/VIL fixed-not VCC-scaled | Higher noise emission at 175 MHz; requires separate level translation when interfacing 1.8 V/3.3 V domains | Choose only if DOC noise suppression is unnecessary and cost is primary constraint |
Compared with SN74AVC16722DGGR, the 74AVC16722DGGRE4 offers identical electrical performance but includes TI's E4 suffix denoting enhanced traceability and controlled manufacturing lot tracking. Against SN74LVC16374DGGR, it provides superior mixed-voltage interoperability and noise-controlled switching-critical for high-density, multi-rail systems.

FAQ
What is the maximum clock frequency supported by the 74AVC16722DGGRE4?
The 74AVC16722DGGRE4 supports up to 175 MHz at VCC = 3.3 V, 140 MHz at 2.5 V, and 80 MHz at 1.2 V, as specified in the timing requirements table. This frequency rating is guaranteed across –40°C to 85°C and reflects worst-case propagation delay (tpd ≤ 2.6 ns at 3.3 V) under recommended operating conditions.
Does the 74AVC16722DGGRE4 support partial-power-down operation?
Yes, the 74AVC16722DGGRE4 includes Ioff circuitry that disables outputs and prevents damaging current backflow when VCC = 0 V. This feature is fully characterized per JESD 78 and allows safe operation in hot-swap or power-gated systems where other rails remain active while VCC is off.
How does the Dynamic Output Control (DOC) circuit in the 74AVC16722DGGRE4 reduce noise?
The DOC circuit in the 74AVC16722DGGRE4 dynamically lowers output impedance at signal transition onset to deliver strong edge drive, then raises it mid-transition to suppress ringing and crosstalk. This achieves ±24 mA dynamic drive at 2.5 V without degrading speed-verified by Figure 1 VOH/VOL vs IOH/IOL curves in the datasheet.
What is the function of the CLKEN pin on the 74AVC16722DGGRE4?
The CLKEN pin on the 74AVC16722DGGRE4 is an asynchronous clock enable input. When CLKEN = L, data on D1–D22 is latched on the rising edge of CLK; when CLKEN = H, the clock is blocked and no new data is stored-preserving prior Q-state regardless of CLK activity.
Is the 74AVC16722DGGRE4 pin-compatible with other 64-pin TSSOP logic devices?
The 74AVC16722DGGRE4 uses the standard DGG (TSSOP-64) footprint defined in MTSS003D, matching mechanical dimensions (12.6 × 6.2 mm, 0.5 mm pitch) and JEDEC MO-153. However, pin functions-including 22 D/Q pairs, dual controls (CLKEN/OE), and distributed VCC/GND-are unique to this 22-bit AVC flip-flop and not interchangeable with generic 64-pin logic ICs.
