Product details
Overview
74ALVT162827DGGY from Nexperia is a 20-bit non-inverting buffer/line driver with integrated 30 Ω termination resistors, dual 10-bit 3-state control (OE1/OE2), bus hold inputs, and BiCMOS output drive. It operates from 2.3 V to 3.6 V, tolerates 5.5 V inputs, and is specified for −40 °C to +85 °C. It enables clean signal routing in high-speed parallel buses such as memory address/data lines or backplane interfaces.
For engineers reviewing the 74ALVT162827DGGY datasheet, 74ALVT162827DGGY pinout, 74ALVT162827DGGY application, or 74ALVT162827DGGY equivalent, key selection criteria include its 30 Ω on-die termination, dual independent 3-state enable architecture, bus hold functionality eliminating external pull-ups, and compatibility with both 2.5 V and 3.3 V logic systems while interfacing safely to 5 V buses.
Technical Context
This device implements two independent 10-bit non-inverting buffers, each controlled by dedicated active-low output enable inputs (1OE0/1OE1 and 2OE0/2OE1). Its BiCMOS output stage delivers strong sink/source current (±12 mA at 3.3 V) while maintaining low propagation delay (1.0–3.3 ns typical) and fast 3-state switching (1.0–5.6 ns).
The integrated 30 Ω series termination resistors per output reduce signal reflections on transmission lines, and bus hold circuitry actively maintains unused input states without external components. IOFF protection ensures minimal leakage during partial power-down, and overvoltage-tolerant inputs support mixed-voltage system interfacing up to 5.5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH162827DGGR | TI part; same 20-bit function, 30 Ω termination, TSSOP56, but requires external VCC tie for bus hold enable | Lacks integrated bus hold activation logic - needs external biasing for unused inputs | Select when TI ecosystem alignment or existing TI qualification is required; verify bus hold implementation in design |
| 74LVC16244ADGG | Nexperia LVC variant; no integrated termination resistors, lower drive (±24 mA), wider VCC range (1.65–3.6 V) | Requires external 30 Ω resistors per output and lacks bus hold - increases BOM and layout effort | Choose for cost-sensitive designs where termination can be added externally and bus hold is managed via system-level pull-ups |
Compared with SN74ALVTH162827DGGR, the 74ALVT162827DGGY integrates autonomous bus hold activation without external biasing; compared with 74LVC16244ADGG, it eliminates 20 discrete terminations and removes dependency on external pull resistors - delivering higher integration and lower system-level design overhead.

FAQ
Does the 74ALVT162827DGGY require external pull-up resistors on unused inputs?
No. The device features integrated bus hold circuitry on all data inputs (1A0–1A9 and 2A0–2A9), which actively maintains the last-valid logic state without external components. This eliminates the need for pull-up or pull-down resistors and prevents floating-input-related noise or metastability in partially populated systems.
Can the 74ALVT162827DGGY safely interface a 3.3 V FPGA to a 5 V legacy bus?
Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC level (2.3–3.6 V), allowing direct connection to 5 V buses. Outputs drive to full rail (VOH ≥ 2.0 V at 3.3 V, VOL ≤ 0.8 V), ensuring compatible logic thresholds with 5 V TTL inputs when used with proper termination.
What is the purpose of the four VCC and eight GND pins in the TSSOP56 package?
The distributed VCC and GND pins minimize power delivery inductance and improve high-frequency noise rejection. Four VCC pins ensure low-impedance supply access across the die; eight GND pins provide dedicated return paths for all 20 outputs and internal logic, reducing ground bounce and crosstalk in high-speed switching applications.
How does the integrated 30 Ω termination differ from standard series termination?
Each output includes a monolithic 30 Ω resistor placed directly at the die bond pad, minimizing parasitic inductance and capacitance. This provides more accurate, consistent, and frequency-stable termination than discrete 0402/0603 resistors - especially critical for edges faster than 1 ns and trace lengths exceeding 2 inches.
