NXP Semiconductors 74LVC162244ADGG:51

Overview

74LVC162244ADGG:51 from Nexperia is a 16-bit non-inverting 3-state buffer/line driver with integrated 30 Ω series output termination resistors, designed for bus interfacing in mixed-voltage systems. It operates from 1.2 V to 3.6 V supply, tolerates 5.5 V on outputs when disabled, and supports 3.3 V/5 V logic level translation - used in high-speed data bus conditioning for industrial PLC backplanes and embedded memory expansion interfaces.

For engineers reviewing the 74LVC162244ADGG:51 datasheet, 74LVC162244ADGG:51 pinout, 74LVC162244ADGG:51 application, or 74LVC162244ADGG:51 equivalent, key selection criteria include its 30 Ω on-die series termination, −40 °C to +125 °C temperature rating, TSSOP48 package compatibility, and four independent 3-state enable inputs enabling flexible multibyte bus control.

Technical Context

This device implements four independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output enable (1OE–4OE). Its CMOS architecture ensures low static power consumption while maintaining TTL-compatible input thresholds and rail-to-rail output swing under load.

The integrated 30 Ω series resistors in both HIGH and LOW output stages suppress transmission-line reflections and reduce EMI in high-speed parallel buses. Inputs accept 0–5.5 V regardless of VCC, enabling safe interfacing between 3.3 V logic domains and legacy 5 V peripherals without external level shifters.

FAQ

What is the maximum operating voltage on the outputs of the 74LVC162244ADGG:51 when VCC = 0 V?

The 74LVC162244ADGG:51 guarantees high-impedance behavior and withstands up to 5.5 V on outputs even when VCC = 0 V. This prevents backfeeding and ensures safe hot-swap operation in modular systems where bus segments may be powered independently. The specification is verified per JEDEC JESD78 and confirmed in Table 4 (Limiting Values) of the official Nexperia datasheet Rev. 6.

Does the 74LVC162244ADGG:51 support 1.2 V logic operation?

Yes, the 74LVC162244ADGG:51 is fully specified down to 1.2 V supply voltage, with propagation delay ≤11.0 ns and guaranteed VIH/VIL thresholds defined in Table 6. This enables direct integration with ultra-low-power microcontrollers and energy-harvesting sensor nodes without level translation. Static and dynamic characteristics at 1.2 V are validated across −40 °C to +125 °C.

How many independent output enable inputs does the 74LVC162244ADGG:51 have?

The 74LVC162244ADGG:51 has four independent active-low output enable inputs: 1OE (pin 1), 2OE (pin 48), 3OE (pin 25), and 4OE (pin 24). Each controls a distinct 4-bit output group (1Y–4Y), allowing granular bus segmentation and partial enablement - critical for power-gated subsystems and multi-master arbitration schemes.

Is the 74LVC162244ADGG:51 pin-compatible with the 74LVCH162244ADGG?

Yes, the 74LVC162244ADGG:51 and 74LVCH162244ADGG share identical TSSOP48 pinout, electrical ratings, and functional behavior. The only difference is that the LVCH variant adds bus-hold circuitry on data inputs - a feature absent in the LVC version. No PCB layout changes are required when substituting between these two parts.

What is the purpose of the 30 Ω series termination resistors inside the 74LVC162244ADGG:51?

The 30 Ω series termination resistors in the 74LVC162244ADGG:51 are integrated into both HIGH and LOW output drivers to match typical PCB trace impedances (40–70 Ω), thereby suppressing signal reflections, reducing overshoot/undershoot, and minimizing EMI. This eliminates the need for 32 external surface-mount resistors in high-speed parallel bus designs, saving board area and assembly cost.
