Product details
Overview
74ALVT16373DGG,118 from Nexperia is a 16-bit transparent D-type latch with 3-state outputs, designed for high-speed bus interface and data buffering in mixed-voltage systems. It operates across 2.3 V to 3.6 V supply, supports 5 V I/O tolerance, delivers ±32 mA/±64 mA output drive, and features dual independent 8-bit latch and output enable controls (1LE/2LE, 1OE/2OE) - used in industrial control backplanes and FPGA I/O expansion.
For engineers reviewing the 74ALVT16373DGG,118 datasheet, 74ALVT16373DGG,118 pinout, 74ALVT16373DGG,118 application, or 74ALVT16373DGG,118 equivalent, key selection criteria include bus-hold input retention, power-up 3-state behavior, propagation delay under 2.5 ns at 3.3 V, and TSSOP48 thermal performance in dense PCB layouts.
Technical Context
This BiCMOS device implements two independent 8-bit transparent latches, each controlled by dedicated latch enable (nLE) and output enable (nOE) inputs. Its bus-hold circuitry actively maintains logic state on unused data inputs without external pull-ups, eliminating floating node risks in hot-swap or partial-configuration scenarios.
The IC supports live insertion/extraction and includes IOFF circuitry enabling partial power-down mode when VCC = 0 V, while maintaining ≤±100 μA off-state leakage. Input clamping tolerates up to 5.5 V regardless of VCC, enabling safe interfacing with legacy 5 V logic buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.3 V to 3.6 V - enables operation in both 2.5 V and 3.3 V system domains |
| Propagation delay (D→Q) | 0.5 ns (min) to 2.5 ns (max) at 3.3 V - ensures sub-3 ns timing margin for 300+ MHz bus cycles |
| Output drive | +64 mA / −32 mA - drives heavy capacitive loads (e.g., >20 pF traces + multiple CMOS inputs) without signal degradation |
| Input voltage tolerance | −0.5 V to +5.5 V - allows direct connection to 5 V TTL/CMOS buses without level shifters |
| Bus-hold current | ±75 μA to ±140 μA at 3 V - sustains valid logic levels on unconnected inputs, preventing metastability |
| Operating temperature | −40 °C to +85 °C - qualified for industrial ambient environments including factory automation controllers |
| IOFF leakage | ±100 μA max at VCC = 0 V - prevents back-powering of powered-down sections during partial system shutdown |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm pitch - optimized for high-density routing and thermal dissipation in compact industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1D0–1D7, 2D0–2D7 | Data inputs (16 total) | Two independent 8-bit input banks; accept 5 V tolerant signals with bus-hold retention |
| 1Q0–1Q7, 2Q0–2Q7 | Data outputs (16 total) | 3-state outputs per bank; driven to high-Z when respective nOE = HIGH |
| 1LE, 2LE | Latch enable (active HIGH) | Controls transparency/latching per 8-bit bank; rising edge captures setup-time-valid data |
| 1OE, 2OE | Output enable (active LOW) | Independent 3-state control per bank; does not affect internal latch state |
| VCC (pins 7,18,31,42) | Supply voltage | Four distributed power pins reduce IR drop and improve noise immunity across wide bus |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | Eight ground pins minimize ground bounce during simultaneous 16-bit switching |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.3 V to 3.6 V operation - eliminates need for separate 2.5 V and 3.3 V regulators in hybrid logic systems |
| 5 V I/O compatibility | Inputs tolerate 5.5 V regardless of VCC - enables direct interconnection with legacy 5 V peripherals without translators |
| Bus-hold inputs | Eliminates external pull-up resistors on unused data lines - reduces BOM count and board space in modular I/O designs |
| Power-up 3-state | Outputs remain high-impedance until VCC stabilizes - prevents bus contention during system power sequencing |
| Live insertion support | IOFF circuitry blocks current flow when VCC = 0 V - allows safe hot-plug replacement in field-replaceable modules |
Applications
| Industrial Backplane Interface | FPGA I/O Expansion |
|---|---|
Use Scenario: Isolating and latching address/data signals between microcontroller and multi-slot backplane with varying slot configurations. IC Role / Device Role / Timing Role: 16-bit transparent latch synchronizing burst transfers; dual LE/OE allows per-slot enable control and glitch-free bus release. Use Value: Bus-hold retains last valid state during slot removal, preventing spurious reads; 2.5 ns propagation enables 400 MB/s throughput at 3.3 V. | Use Scenario: Extending limited FPGA I/O pins to drive external memory, sensors, and actuators in programmable logic controllers. IC Role / Device Role / Timing Role: Bidirectional data buffer with independent 8-bit banks - one bank latches sensor inputs, the other drives actuator outputs. Use Value: 5 V tolerance interfaces directly with industrial sensors; power-up 3-state prevents FPGA configuration conflict during boot. |
| Hot-Swappable Module Control | Legacy System Bus Bridging |
Use Scenario: Managing communication between main controller and field-replaceable compute modules in telecom base stations. IC Role / Device Role / Timing Role: Latch and isolate module-specific control/status registers during insertion/removal events. Use Value: Live insertion support and IOFF protection prevent back-feeding into powered-down modules; ±64 mA drive handles long trace runs. | Use Scenario: Interfacing modern 3.3 V SoCs with legacy 5 V ISA or PCI bus peripherals in test equipment upgrades. IC Role / Device Role / Timing Role: Voltage-tolerant latch buffering bidirectional data paths while maintaining timing integrity across voltage domains. Use Value: Eliminates discrete level shifters; 4.2 ns max tPHL at 2.5 V meets ISA bus timing requirements for 8 MHz operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transparent latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH16373ZRGR | TI part; same 16-bit latch function but uses different BiCMOS process; slightly higher ICC (0.15 mA vs 0.1 mA) and lower VOL (0.25 V vs 0.4 V at 32 mA) | Optimized for TI ecosystem reference designs; lacks Nexperia's bus-hold overdrive current spec (IBHHO/IBHLO) | Select when using TI PowerPAD layout tools or requiring tighter VOL in high-current drive scenarios |
| 74LVT16373DGG,118 | Nexperia pin-compatible variant; operates only at 3.0 V to 3.6 V (no 2.3–2.7 V range); no bus-hold inputs; lower output drive (±24 mA) | Suitable for cost-sensitive 3.3 V-only designs where unused inputs are externally terminated | Select only if bus-hold is unnecessary and supply is strictly regulated at 3.3 V ±0.3 V |
Compared with SN74ALVTH16373ZRGR, the 74ALVT16373DGG,118 offers superior bus-hold robustness and wider voltage flexibility; compared with 74LVT16373DGG,118, it adds critical 2.5 V compatibility and active input retention - essential for mixed-supply industrial systems.

FAQ
Does the 74ALVT16373DGG,118 require external pull-up resistors on unused inputs?
No. The device integrates bus-hold circuitry on all data inputs (1D0–1D7, 2D0–2D7), providing ±75 μA to ±140 μA holding current at 3 V to maintain valid logic states without external components - verified per Table 6 IBHL/IBHH specs in the Rev. 7 datasheet.
What is the maximum clock frequency supported for transparent latch operation?
The device has no internal clock; it operates asynchronously. Maximum effective data rate is governed by propagation delay (tPLH/tPHL ≤ 2.5 ns at 3.3 V) and setup/hold times (tsu(L) ≥ 0.8 ns, th(L) ≥ 1.0 ns). This supports reliable 300+ MHz bus toggling when paired with appropriate edge-aligned control signals.
Can the 74ALVT16373DGG,118 be used in a 5 V system?
Yes - its inputs tolerate up to +5.5 V regardless of VCC, and outputs drive 5 V-tolerant loads. However, VCC must remain within 2.3 V to 3.6 V. It interfaces safely with 5 V buses (e.g., legacy ISA, parallel ports) while operating from a 3.3 V rail, eliminating level shifters.
How does the power-up 3-state feature behave during system startup?
At power-on, outputs enter high-impedance state before VCC reaches valid operating range and remain there until VCC stabilizes - confirmed by "Power-up 3-State" in Section 2 and VOH/VOL(pu) specs in Table 6. This prevents bus contention during power-rail ramp-up, critical in multi-device shared-bus systems.
