Product details
Overview
74ALVT162827DGG,11 from Nexperia is a 20-bit non-inverting 3-state buffer/line driver with integrated 30 Ω termination resistors, dual independent output-enable controls (OE1/OE2), bus-hold inputs, and BiCMOS output drive. It operates from 2.3 V to 3.6 V, supports 5.5 V-tolerant inputs, and is specified for -40 °C to +85 °C. It is used in high-speed parallel bus interfaces requiring impedance-matched signal integrity, such as backplane or memory subsystem drivers.
For engineers reviewing the 74ALVT162827DGG,11 datasheet, 74ALVT162827DGG,11 pinout, 74ALVT162827DGG,11 application, or 74ALVT162827DGG,11 equivalent, this page delivers verified functional identity, TSSOP56 package mapping, 20-pin input/output pairing per bank, bus-hold behavior, and 30 Ω on-die termination - all confirmed from Nexperia's Rev. 4 product data sheet (June 2024).
Technical Context
This device implements two independent 10-bit buffered paths, each with separate active-low output enables (1OE0/1OE1 and 2OE0/2OE1), enabling selective 10-bit bus gating. Its BiCMOS architecture delivers TTL-compatible output drive while maintaining low static current and fast propagation (as low as 1.0 ns tPHL at 3.3 V).
The integrated 30 Ω series termination resistors are placed directly at each output pin (e.g., 1Y0–1Y9, 2Y0–2Y9), reducing external component count for controlled-impedance transmission lines. Bus-hold circuitry actively maintains unused input logic states without external pull-ups, with IBHL = 75–130 μA (VCC = 3 V) and IBHH = −75 to −140 μA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 20-bit non-inverting 3-state buffer with dual 10-bit enable control and on-die 30 Ω series termination |
| Supply voltage | 2.3 V to 3.6 V - supports mixed-voltage system interfacing (e.g., 2.5 V core to 3.3 V I/O) |
| Input tolerance | 5.5 V overvoltage tolerant - allows safe connection to 5 V buses without level shifters |
| Propagation delay | 1.0 ns (tPHL, typ.) at 3.3 V - enables >300 MHz bus operation with tight timing margins |
| Output drive | ±12 mA (IOL/IOH) - sufficient to drive 50 Ω transmission lines terminated to VCC or GND |
| Bus hold current | IBHL = 75–130 μA, IBHH = −75 to −140 μA - eliminates need for external pull resistors on floating inputs |
| Operating temperature | −40 °C to +85 °C - qualified for industrial-grade embedded and communications equipment |
Pinout & Package
TSSOP56 (SOT364-1) package: plastic thin shrink small outline, 56 leads, 6.1 mm body width, 1.2 mm max height, 0.5 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A0–1A9 (pins 55,54,52,51,49,48,47,45,44,43) | Data input bank 1 | 10-bit parallel input group controlled by OE1; bus-hold enabled |

| 1OE0/1OE1 (pins 1,56), 2OE0/2OE1 (pins 28,29) | Active-low output enables | Each pair gates one 10-bit bank; HIGH forces corresponding outputs to high-impedance |
| VCC (pins 7,22,35,50) | Positive supply | Four distributed power pins reduce IR drop and improve noise immunity |
| GND (pins 4,11,18,25,32,39,46,53) | Ground reference | Eight ground pins provide low-inductance return paths for all I/O banks |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 10-bit 3-state control | Separate OE0/OE1 per bank enables flexible bus partitioning without external logic |
| Integrated 30 Ω series termination | Eliminates 20 discrete 30 Ω resistors, saving PCB area and improving signal integrity on high-speed traces |
| Bus-hold inputs | Maintains valid logic state on unconnected or unterminated inputs - no external pull-up/down required |
| Power-up 3-state and IOFF protection | Outputs remain high-impedance during power ramp-up; IOFF limits leakage when VCC = 0 V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 20-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH162827DGGR | TI part with identical pinout and 30 Ω termination, but wider VCC range (2.3–3.6 V same); slightly higher ICC (0.15 mA vs 0.07 mA) | Same bus-hold and 5.5 V tolerance; lower tPHL (0.9 ns typ.) but tighter layout constraints due to thermal pad | Select if TI ecosystem alignment or marginally faster timing is prioritized over ultra-low quiescent current |
| 74LVC16244ADGG,118 | No integrated termination; requires external 33 Ω resistors; lower drive (±24 mA); no bus-hold; 3.6 V max VCC only | Higher board-level design effort for termination; lacks input state retention; suitable only where cost-per-pin is primary | Choose only when termination is implemented externally and bus-hold is unnecessary - not drop-in compatible |
Compared with SN74ALVTH162827DGGR, the 74ALVT162827DGG,11 offers lower static power and identical timing performance; versus 74LVC16244ADGG,118, it delivers plug-and-play signal integrity and robustness for unmanaged inputs - making it superior for high-reliability industrial and test systems.

FAQ
Does the 74ALVT162827DGG,11 support hot-swap or live-insertion?
No. While the device features IOFF circuitry that limits power-off leakage (<±100 μA), it lacks explicit hot-swap protection such as slew-rate controlled outputs or undervoltage lockout. Insertion into a live backplane may cause transient bus contention or ground bounce; proper power sequencing and edge-rate control on OE lines are required for safe operation.
Can the 30 Ω termination resistors be bypassed or disabled?
No. The 30 Ω resistors are monolithically integrated in series with each output driver and cannot be disabled or shorted. They are permanently part of the output path. If termination is not required, an alternative part without on-die resistors (e.g., 74ALVT162244) must be selected.
What is the maximum sustained output current per pin?
The absolute maximum output current per pin is ±128 mA (per Table 4), but the recommended operating condition limits continuous DC output current to ±12 mA (Table 5). Sustained operation above ±12 mA risks thermal overload and violates the device's specified reliability envelope - use only for brief transient loads.
How does bus-hold behave when VCC is below 2.3 V?
Bus-hold functionality is not guaranteed below VCC = 2.3 V. Per Section 9, IBHL and IBHH parameters are characterized only at VCC ≥ 2.3 V (2.5 V ± 0.2 V) and VCC ≥ 3.0 V (3.3 V ± 0.3 V). Below 2.3 V, input states may float or become unstable; power sequencing must ensure VCC reaches minimum before applying input signals.
