Product details

Overview

SN74LVCZ16245ADGVR from Texas Instruments is a 16-bit noninverting bus transceiver with 3-state outputs, designed for asynchronous bidirectional data transfer between 2.7-V to 3.6-V buses. It supports mixed-mode signaling (5-V inputs with 3.3-V V_CC), delivers max propagation delay of 3.7 ns at 3.3 V, and features I_off and power-up 3-state for hot-insertion in backplane or modular systems.

For engineers reviewing the SN74LVCZ16245ADGVR datasheet, SN74LVCZ16245ADGVR pinout, SN74LVCZ16245ADGVR application, or SN74LVCZ16245ADGVR equivalent, key selection criteria include 48-pin TVSOP package compatibility, 5.5-V tolerant inputs, dual-octal directional control (DIR/OE), and verified hot-swap capability per JESD 78 Class II latch-up performance.

Technical Context

The SN74LVCZ16245ADGVR implements two independent 8-bit transceiver sections, each with separate DIR and OE controls, enabling flexible A↔B or B↔A data flow routing without external logic. Its I_off circuitry actively disables outputs during power-down to prevent backflow current, while power-up 3-state ensures high-impedance outputs until V_CC exceeds 1.5 V.

Input voltage tolerance up to 5.5 V allows direct interfacing with legacy 5-V logic in mixed-voltage systems, and output drive strength is specified at ±24 mA (V_CC = 3 V), supporting standard LVTTL loads. The device operates across –40°C to 85°C and meets JESD 22 ESD ratings (2000-V HBM, 1000-V CDM).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.7 V to 3.6 V - Ensures stable operation in modern low-voltage digital systems while maintaining backward compatibility with 3.3-V infrastructure.
Input Voltage Tolerance	Up to 5.5 V - Enables direct connection to 5-V sources without level-shifting circuitry in mixed-voltage bus interfaces.
Max Propagation Delay	3.7 ns at 3.3 V - Supports high-speed data transfer in real-time communication links such as memory expansion or peripheral interconnects.
I_off Support	Yes - Prevents damaging current backflow during hot insertion or partial power-down, critical for modular computing and telecom line cards.
Output Drive Strength	±24 mA at V_CC = 3 V - Sufficient to drive multiple LVTTL inputs or short PCB traces without signal degradation.
Latch-Up Performance	>100 mA per JESD 78 Class II - Guarantees robustness against transient overcurrent events in industrial environments.
ESD Protection	2000-V HBM, 1000-V CDM - Meets stringent reliability requirements for handling and board assembly in production lines.

Pinout & Package

SN74LVCZ16245ADGVR uses a 48-pin Thin Very Small Outline Package (TVSOP, DGV), measuring 12.6 mm × 6.2 mm × 1.2 mm max height, compliant with JEDEC MO-153 and optimized for high-density PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR	Direction control input	Determines data flow direction per 8-bit section: DIR = L enables B→A; DIR = H enables A→B.
1OE, 2OE	Output enable input	Active-low control: OE = L enables transceiver; OE = H places all outputs in high-impedance state for bus isolation.
1A1–1A8, 2A1–2A8	Port A I/O terminals	First and second 8-bit data bus interface on A side; tolerate 0–5.5 V regardless of V_CC.
1B1–1B8, 2B1–2B8	Port B I/O terminals	Corresponding 8-bit data bus interface on B side; fully symmetrical with Port A for bidirectional use.
V_CC (Pins 7, 18, 29, 40)	Power supply	Four dedicated V_CC pins reduce switching noise and improve power integrity across high-speed operation.
GND (Pins 4, 11, 22, 33, 44)	Ground reference	Five GND pins provide low-inductance return paths, minimizing ground bounce in 16-bit parallel data transfers.

Key Features

Feature	Design Value
Mixed-mode signal operation	5-V-tolerant inputs with 3.3-V V_CC eliminate need for external level shifters in 3.3/5-V system bridges.
Hot-insertion support	I_off and power-up 3-state ensure safe insertion/removal in live backplanes without disrupting adjacent modules.
Dual independent 8-bit control	Separate DIR/OE per octal section allows asymmetric bus management-e.g., one direction active while other isolated.
Low dynamic power consumption	4 pF power-dissipation capacitance when outputs disabled reduces system-level standby current in portable applications.
Robust ESD/latch-up immunity	Exceeds JESD 22 and JESD 78 requirements, enabling reliable deployment in uncontrolled industrial or field-replaceable units.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC16245A	Lacks Z-series I_off and enhanced hot-swap features; identical pinout and DC specs.	Suitable only for cold-plug or fixed-installation systems where power sequencing is controlled.	Select SN74LVC16245A only if hot-insertion is not required and cost optimization is prioritized.
74ALVC16245	Higher speed (t_pd = 2.8 ns @ 3.3 V) but no 5.5-V input tolerance; requires strict 2.3–3.6 V V_CC.	Better for ultra-low-latency internal bus extensions where voltage rails are tightly regulated.	Choose 74ALVC16245 only when sub-3-ns propagation is mandatory and mixed-voltage interfacing is absent.

Compared with SN74LVC16245A and 74ALVC16245, the SN74LVCZ16245ADGVR uniquely combines 5.5-V input tolerance, I_off-enabled hot-swap safety, and 3.7-ns timing-making it the sole choice for field-upgradeable, mixed-voltage industrial backplanes.

FAQ

What is the maximum operating temperature range for the SN74LVCZ16245ADGVR?

The SN74LVCZ16245ADGVR is rated for operation from –40°C to +85°C ambient temperature, validated per its recommended operating conditions table and qualified for industrial-grade thermal performance. This range applies to the TVSOP (DGV) package variant and is confirmed in TI's official packaging addendum and electrical characteristics tables.

Does the SN74LVCZ16245ADGVR support true 5-V to 3.3-V level translation?

Yes, the SN74LVCZ16245ADGVR supports true bidirectional level translation: inputs accept up to 5.5 V regardless of V_CC (2.7–3.6 V), and outputs swing rail-to-rail between GND and V_CC. This enables reliable 5-V logic driving into the device while delivering 3.3-V-compatible outputs-confirmed in the "Mixed-Mode Signal Operation" section of the SCES278D datasheet.

Can the SN74LVCZ16245ADGVR be used in hot-swap applications without additional protection circuitry?

Yes, the SN74LVCZ16245ADGVR integrates both I_off and power-up 3-state functionality, explicitly designed for hot-insertion. When V_CC is below 1.5 V or ramping, outputs remain in high-impedance state, preventing bus contention and back-current flow-verified in functional description and absolute maximum ratings sections of the datasheet.

What is the pin count and package type of the SN74LVCZ16245ADGVR?

The SN74LVCZ16245ADGVR uses a 48-pin Thin Very Small Outline Package (TVSOP), designated DGV per TI's package drawings. Its dimensions are 12.6 mm × 6.2 mm × 1.2 mm max height, and it complies with JEDEC MO-153 mechanical standards-documented in TI's MPDS006C mechanical data sheet and packaging addendum.

How does the SN74LVCZ16245ADGVR handle power sequencing during system startup?

The SN74LVCZ16245ADGVR employs power-up 3-state logic that forces all outputs into high-impedance until V_CC exceeds 1.5 V, eliminating bus conflicts during uncontrolled power ramp-up. For guaranteed isolation above 1.5 V, TI recommends tying OE to V_CC via a pullup resistor-details appear in the "description/ordering information" section of SCES278D.
