Product details
Overview
IDT74LVC16501APAG from Integrated Device Technology is a 3.3V CMOS 18-bit registered transceiver with 3-state outputs, 5V-tolerant I/O, ±24mA drive strength, and industrial temperature range (–40°C to +85°C). It supports bidirectional data flow in transparent, latched, and clocked modes for mixed-voltage bus interfacing in telecom backplanes and industrial control systems.
For engineers reviewing the IDT74LVC16501APAG datasheet, IDT74LVC16501APAG pinout, IDT74LVC16501APAG application, or IDT74LVC16501APAG equivalent, key selection criteria include output skew (<500 ps), 5V-tolerant inputs/outputs, dual-clock/latch control per direction, and SSOP-56 package compatibility with high-density PCB layouts.
Technical Context
The IDT74LVC16501APAG implements two independent 18-bit data paths (A↔B) with separate clock (CLKAB/CLKBA), latch enable (LEAB/LEBA), and output-enable (OEAB/OEBA) controls. Each path supports transparent mode (LE high), edge-triggered latching (LE low + CLK transition), and 3-state output control - enabling precise timing coordination in synchronous bus architectures.
All I/O pins are 5V tolerant across VCC = 2.7V–3.6V operation, with hysteresis on inputs for noise immunity and ±24mA push-pull drivers optimized for driving moderate capacitive loads while maintaining tPLH/tPHL ≤ 4.6 ns at 3.3V. Output skew is specified at ≤500 ps between any two outputs switching in the same direction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports both normal (3.3V ±0.3V) and extended supply operation in mixed-voltage systems |
| Drive Strength | ±24mA - enables direct interface to legacy 5V TTL loads without level-shifting circuitry |
| Output Skew | ≤500ps - ensures deterministic timing alignment across all 18 outputs during parallel data transfer |
| I/O Voltage Tolerance | 0V to 6.5V terminal voltage - allows safe connection to 5V signal sources while powered from 3.3V |
| Propagation Delay | tPLH/tPHL ≤ 4.6ns @ 3.3V - meets timing budgets for 150MHz bus operation with margin |
| Input Hysteresis | 100mV @ 3.3V - improves noise rejection on control signals in electrically noisy industrial environments |
| Quiescent ICC | ≤10µA - minimizes standby power in always-on communication subsystems |
Pinout & Package
Package: 56-pin Shrink Small Outline Package (SSOP), lead-free and green-compliant (PAG suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OEAB | A-to-B Output Enable (Active HIGH) | Enables B-port outputs when HIGH; places them in high-impedance state when LOW |
| OEBA | B-to-A Output Enable (Active LOW) | Enables A-port outputs when LOW; disables them when HIGH - supports active-low bus arbitration |
| LEAB / LEBA | Latch Enable (A→B and B→A) | Controls transparent vs. latched mode: HIGH = transparent, LOW + CLK edge = store data |
| CLKAB / CLKBA | Clock Input (A→B and B→A) | Edge-triggered sampling of A or B bus data when corresponding LE is LOW |
| A1–A18 | A-port I/O (bidirectional) | Function as inputs (B→A) or 3-state outputs (A→B) depending on OEBA/OEAB states |
| B1–B18 | B-port I/O (bidirectional) | Function as inputs (A→B) or 3-state outputs (B→A) depending on OEAB/OEBA states |

Equivalent & Alternatives
The following parts are listed as comparable options for similar registered transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16501ADGGR | 56-pin TSSOP package; identical electrical specs but lower profile (1.2mm max height vs. SSOP's 2.0mm) | Better suited for space-constrained portable test equipment where Z-height is critical | Select SN74LVC16501ADGGR if board stack height is constrained and thermal mass requirements permit TSSOP mounting. |

FAQ
What is the maximum clock frequency supported by the IDT74LVC16501APAG?
The IDT74LVC16501APAG supports a maximum clock frequency of 150 MHz, as specified in its switching characteristics table under fMAX at VCC = 2.7V and VCC = 3.3V ±0.3V. This rating applies to both CLKAB and CLKBA inputs and assumes proper load conditions (CL ≤ 50 pF) and signal integrity margins. The IDT74LVC16501APAG achieves this performance while maintaining tPLH/tPHL ≤ 4.6 ns and output skew ≤ 500 ps, making it suitable for high-speed synchronous bus applications.
Does the IDT74LVC16501APAG support hot insertion?
Yes, the IDT74LVC16501APAG supports hot insertion, as explicitly stated in its official features list. This capability is enabled by its 5V-tolerant I/O structure, power-off protection (IOFF ≤ ±50 µA), and controlled output-enable sequencing - allowing safe insertion/removal in live backplane systems without disrupting upstream or downstream logic. The IDT74LVC16501APAG maintains this behavior across its full industrial temperature range (–40°C to +85°C).
What is the meaning of the 'PAG' suffix in IDT74LVC16501APAG?
The 'PAG' suffix in IDT74LVC16501APAG indicates a lead-free, green-compliant 56-pin Shrink Small Outline Package (SSOP) with standard pin pitch (0.635 mm) and body dimensions (18.4 mm × 7.5 mm). 'P' denotes SSOP, 'A' specifies industrial temperature grade (–40°C to +85°C), and 'G' confirms RoHS-compliant, halogen-free construction. This package variant is mechanically and electrically identical to the 'PA' version but meets modern environmental compliance standards required for global industrial deployments.
Can the IDT74LVC16501APAG operate with a 2.5V supply?
No, the IDT74LVC16501APAG is not rated for 2.5V operation. Its absolute minimum VCC is 2.7V, and DC electrical specifications (VIH, VOL, VOH, etc.) are only guaranteed across VCC = 2.7V to 3.6V. While some functionality may appear at 2.5V in lab conditions, the IDT74LVC16501APAG does not meet timing, drive strength, or noise margin specifications below 2.7V - and operation outside this range voids parametric guarantees per the datasheet's Absolute Maximum Ratings table.
How does the latch enable (LE) function differ from the clock (CLK) function in the IDT74LVC16501APAG?
In the IDT74LVC16501APAG, LEAB/LEBA determines operational mode: when HIGH, the device operates in transparent mode (A↔B data passes through); when LOW, it enters latched mode. In latched mode, CLKAB/CLKBA then controls data capture - storing A or B bus values on the low-to-high transition. Thus, LE sets the mode, and CLK triggers storage only when LE is asserted low. This two-signal control enables flexible synchronization strategies not possible with clock-only registers, and is fundamental to the IDT74LVC16501APAG's role in deterministic bus interfacing.
