Product details
Overview
74LVCH322244AEC,51 from NXP Semiconductors is a 32-bit non-inverting buffer/line driver with 3-state outputs, integrated 30 Ω series termination resistors, 5 V tolerant I/O, and bus hold on all data inputs. It operates from 1.2 V to 3.6 V supply and supports mixed-voltage interfacing between 3.3 V and 5 V logic domains in high-speed digital backplanes and memory interfaces.
For engineers reviewing the 74LVCH322244AEC,51 datasheet, 74LVCH322244AEC,51 pinout, 74LVCH322244AEC,51 application, or 74LVCH322244AEC,51 equivalent, this device delivers deterministic propagation delay (as low as 1.0 ns at 3.0–3.6 V), sub-8 ns enable/disable timing, and JEDEC-compliant voltage operation across −40 °C to +125 °C - critical for industrial control and telecom infrastructure design.
Technical Context
This IC implements eight independent 4-bit non-inverting buffers, each with dedicated active-low 3-state output enable (nOE) and bus-hold circuitry on all A[0:3] inputs. Each output stage integrates matched 30 Ω series resistors in both HIGH and LOW states to suppress transmission-line reflections without external components.
The LFBGA96 package provides low-inductance multiple VCC and GND balls (8 VCC, 16 GND) to minimize ground bounce and noise coupling. Input clamping allows safe 5.5 V input overvoltage while powered from 1.2–3.6 V, and 3-state outputs tolerate up to 5.5 V during high-impedance mode - enabling robust level translation in hot-swap and mixed-supply systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC32244PAG | Same 32-bit non-inverting 3-state architecture but in 100-pin TQFP; no integrated 30 Ω termination; bus hold only on data inputs | Lacks on-die termination - requires external series resistors for controlled-impedance traces; higher board area usage | Select when footprint constraints favor TQFP or when termination is implemented externally for tuning flexibility |
| 74ALVCH322244AEC,51 | Pin-compatible variant with wider supply range (1.65–3.6 V only); identical pinout, bus hold, and 5 V tolerance; lower ICC (10 µA typical vs. 40 µA) | Optimized for ultra-low static power in battery-backed systems; same dynamic performance and thermal rating | Select for energy-sensitive applications where quiescent current below 20 µA is mandatory and 1.2 V operation is not required |
Compared with SN74LVC32244PAG and 74ALVCH322244AEC,51, the 74LVCH322244AEC,51 uniquely combines on-die 30 Ω termination, 1.2 V minimum supply, and full −40 °C to +125 °C qualification - making it the only option supporting both lowest-voltage operation and impedance-controlled signaling in compact LFBGA form factor.

FAQ
What is the minimum supply voltage supported by the 74LVCH322244AEC,51?
The 74LVCH322244AEC,51 supports a minimum supply voltage of 1.2 V, enabling compatibility with ultra-low-voltage microcontrollers and FPGAs. This is confirmed in Table 5 (Recommended Operating Conditions) of the NXP datasheet Rev. 3, where functional operation is specified down to 1.2 V - a key differentiator versus standard LVC-family buffers limited to 1.65 V minimum.
Does the 74LVCH322244AEC,51 require external pull-up resistors on its nOE inputs?
Yes - to ensure high-impedance state during power-up or power-down, each nOE input must be tied to VCC via an external pull-up resistor. The minimum value depends on the driver's current-sinking capability, as stated in the General Description section. Bus hold is not provided on nOE pins, only on data inputs (A[0:3]).
Can the 74LVCH322244AEC,51 safely interface with 5 V logic while powered from 3.3 V?
Yes - the 74LVCH322244AEC,51 features 5 V tolerant inputs and 3-state outputs, allowing it to accept 5.5 V input signals and drive 5.5 V loads in high-impedance mode while operating from a 3.3 V supply. This is explicitly verified in Tables 4 (Limiting Values) and 5 (Recommended Operating Conditions) of the datasheet.
How does the integrated 30 Ω series termination in the 74LVCH322244AEC,51 improve signal integrity?
The 30 Ω series termination resistors in both HIGH and LOW output stages match typical PCB trace impedances (e.g., 50–60 Ω single-ended), suppressing reflections and reducing ringing without requiring external components. This directly lowers EMI and improves timing margins - validated by measured tpd skew ≤1.5 ns and clean edges in Figure 4 and Table 7.
Is the 74LVCH322244AEC,51 qualified for automotive applications?
No - the 74LVCH322244AEC,51 is rated for −40 °C to +125 °C operation but is not automotive-qualified. As stated in Section 15.3 of the datasheet, unless explicitly marked "automotive qualified", NXP products are not tested to AEC-Q100 standards and are not warranted for safety-critical vehicle systems.
