Product details

Overview

74ALVT16501DGG,112 from Nexperia is an 18-bit universal bus transceiver in TSSOP56 package, operating at 2.5 V or 3.3 V with 5 V I/O tolerance. It provides bidirectional data flow between A- and B-buses using independent latch/flip-flop control (LEAB/LEBA), clocked transfer (CPAB/CPBA), and complementary 3-state enables (OEAB active HIGH, OEBA active LOW). It supports high-speed computing interconnects requiring bus hold, live insertion, and power-up 3-state.

For engineers reviewing the 74ALVT16501DGG,112 datasheet, 74ALVT16501DGG,112 pinout, 74ALVT16501DGG,112 application, or 74ALVT16501DGG,112 equivalent, key selection criteria include propagation delay ≤2.9 ns (VCC = 3.3 V), ±64 mA output drive, 5 V tolerant I/O, bus hold functionality eliminating external pull-ups, and compatibility with TTL/LVTTL logic levels in industrial and embedded backplane interfaces.

Technical Context

The 74ALVT16501DGG,112 implements a BiCMOS architecture enabling dual-supply operation (2.5 V/3.3 V) while maintaining 5 V I/O compatibility. Its dual-path control logic allows independent A-to-B and B-to-A data routing with separate latch enable, clock, and output enable inputs for each direction.

It features positive-edge-triggered clock inputs (CPAB/CPBA), active HIGH and active LOW complementary output enables (OEAB/OEBA), and integrated bus hold circuitry on all data inputs to maintain valid logic states without external resistors - critical for hot-swap and floating-bus reliability.

28 (LEBA)	B-to-A latch enable	Enables B-to-A data latching on rising CPBA edge - provides full-duplex register control
55 (CPAB)	A-to-B clock	Rising-edge triggered; samples A-bus when LEAB is LOW - defines precise timing for registered transfers
30 (CPBA)	B-to-A clock	Rising-edge triggered; samples B-bus when LEBA is LOW - ensures deterministic latency in reverse path
3–26, 31–54 (A0–A17, B0–B17)	Bidirectional data I/O	18-bit A-side and 18-bit B-side ports with 5 V tolerant inputs and bus-hold - supports hot-pluggable backplane links
4, 11, 18, 25, 29, 32, 39, 46, 53, 56 (GND)	Ground	10 dedicated GND pins - reduces ground bounce and improves noise immunity in high-speed switching

Equivalent & Alternatives

The following parts are listed as comparable options for similar universal bus transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74ALVT16501DL,118	SSOP56 package (SOT371-1), 7.5 mm body width, higher thermal resistance (θJA = 65 °C/W vs. 55 °C/W for TSSOP)	Preferred where manual assembly or legacy footprint compatibility required; less suitable for high-density automated SMT lines	Select when board layout uses SSOP56 land pattern or thermal derating above 55 °C ambient is acceptable
SN74ALVTH16501GR	Texas Instruments part; identical function but different AC specs - tPLH = 2.3 ns (typ, 3.3 V), lower drive (−32/+32 mA), no bus hold	Requires external pull-ups; not suitable for hot-swap or floating-bus scenarios where bus hold is critical	Choose only if TI supply chain preference exists and bus hold functionality is implemented externally

Compared with 74ALVT16501DL,118, the 74ALVT16501DGG,112 offers superior thermal performance and smaller footprint; versus SN74ALVTH16501GR, it delivers stronger drive, integrated bus hold, and tighter propagation delay - making it optimal for high-reliability, high-density, and hot-swap-critical designs.

FAQ

What is the maximum clock frequency supported by the 74ALVT16501DGG,112?

The 74ALVT16501DGG,112 supports a maximum clock frequency of 150 MHz under recommended operating conditions (VCC = 3.3 V, CL = 50 pF). This rating applies to both CPAB and CPBA inputs and is validated across the full industrial temperature range (−40 °C to +85 °C), ensuring reliable synchronous operation in high-speed digital systems.

Does the 74ALVT16501DGG,112 require external pull-up resistors on its data lines?

No, the 74ALVT16501DGG,112 does not require external pull-up resistors. It integrates active bus hold circuitry on all 36 data I/O pins (A0–A17 and B0–B17), which maintains valid logic levels on unused or floating inputs. This feature eliminates the need for 36 discrete pull-up resistors, reducing BOM cost, PCB area, and potential signal integrity issues.

Can the 74ALVT16501DGG,112 operate with a 2.5 V supply while interfacing with 5 V logic?

Yes, the 74ALVT16501DGG,112 is fully specified for 2.5 V supply operation (VCC = 2.5 V ±0.2 V) while supporting 5 V-tolerant I/O - inputs accept up to 5.5 V, and outputs drive 5 V buses safely. This enables seamless interfacing between newer low-voltage cores and legacy 5 V peripherals without external level-shifting components.

What is the meaning of complementary output enables OEAB and OEBA on the 74ALVT16501DGG,112?

On the 74ALVT16501DGG,112, OEAB is active HIGH (enables A-to-B outputs when HIGH), while OEBA is active LOW (enables B-to-A outputs when LOW). This complementary polarity allows simultaneous 3-state control of both directions using a single pair of anti-phased control signals - simplifying bus arbitration logic in full-duplex systems.

Is the 74ALVT16501DGG,112 suitable for hot-swap applications?

Yes, the 74ALVT16501DGG,112 is explicitly designed for hot-swap applications. It features power-up 3-state (outputs remain high-impedance until VCC stabilizes), live insertion/extraction support, and bus hold - collectively preventing bus contention, glitches, or damage during card insertion/removal in modular systems like telecom shelves or industrial racks.
