Product details
Overview
74LVCH32244AEC/G:5 from NXP Semiconductors (formerly Philips) is a 32-bit non-inverting buffer/line driver with 3-state outputs, 5 V-tolerant I/O, bushold inputs, and operation across 1.2 V to 3.6 V supply. It features eight independent output-enable inputs (1OE–8OE), 96-ball LFBGA package, and supports mixed-voltage interfacing between 3.3 V and 5 V systems in high-density PCBs.
For engineers reviewing the 74LVCH32244AEC/G:5 datasheet, 74LVCH32244AEC/G:5 pinout, 74LVCH32244AEC/G:5 application, or 74LVCH32244AEC/G:5 equivalent, key selection criteria include 5 V I/O tolerance, bushold input retention, propagation delay ≤4.1 ns at 3.3 V, 3-state enable/disable timing under 4.6 ns, and LFBGA96 thermal/mechanical suitability for industrial embedded bus interfaces.
Technical Context
The 74LVCH32244AEC/G:5 implements eight independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output-enable input (nOE). All 32 data inputs feature bushold circuitry, eliminating external pull-ups for floating or unused pins.
It operates across 1.2 V–3.6 V VCC while accepting input voltages up to 5.5 V and driving outputs to 5.5 V in 3-state mode. Propagation delay (tPHL/tPLH) is 3.0 ns typical at VCC = 3.3 V, CL = 50 pF; 3-state enable (tPZH/tPZL) and disable (tPHZ/tPLZ) times are 3.5 ns and 3.7 ns typical under identical conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3244APAG | 48-pin TSSOP package; no bushold; 1.65 V–3.6 V VCC range; 5 V-tolerant I/O retained | Lacks bushold functionality; requires external pull-ups on unused inputs; lower pin count limits channel grouping flexibility | Select when board space permits larger TSSOP and bushold is not required for floating input management |
| 74ALVCH32244AEC | Same LFBGA96 package and pinout; wider VCC range (1.65 V–3.6 V); higher speed (2.4 ns typical tPHL at 3.3 V) | Higher performance but reduced low-voltage headroom below 1.65 V; identical bushold and 5 V tolerance | Select when sub-1.65 V operation is unnecessary and maximum propagation speed is critical for timing-closure |
Compared with 74LVCH32244AEC/G:5, SN74LVC3244APAG trades bushold and fine-pitch packaging for through-hole assembly compatibility, while 74ALVCH32244AEC delivers faster timing at the cost of minimum supply voltage flexibility - both require revalidation of input biasing and thermal layout.

FAQ
What is the minimum supply voltage required for reliable operation of the 74LVCH32244AEC/G:5?
The 74LVCH32244AEC/G:5 operates reliably down to 1.2 V VCC, as specified in the Recommended Operating Conditions table. At this voltage, propagation delay increases to 11.0 ns max (CL = 50 pF), and bushold functionality remains active. For guaranteed timing performance below 2.7 V, consult AC characteristics tables specifying VCC-dependent limits.
Does the 74LVCH32244AEC/G:5 require external pull-up resistors on its data inputs?
No, the 74LVCH32244AEC/G:5 does not require external pull-up resistors on its data inputs because all 32 data inputs incorporate bushold circuitry. This internal feature actively maintains the last-valid logic state on floating or unused inputs, eliminating the need for discrete components and reducing board-level complexity.
Can the 74LVCH32244AEC/G:5 safely interface with 5 V TTL logic while powered from a 2.5 V supply?
Yes, the 74LVCH32244AEC/G:5 can safely interface with 5 V TTL logic while powered from 2.5 V VCC. Its inputs tolerate up to 5.5 V regardless of supply voltage, and its 3-state outputs can drive up to 5.5 V when disabled - enabling seamless bidirectional voltage translation without external level shifters.
How many independent 3-state control inputs does the 74LVCH32244AEC/G:5 provide?
The 74LVCH32244AEC/G:5 provides eight independent active-low 3-state output-enable inputs: 1OE through 8OE. Each controls a dedicated 4-bit buffer group (e.g., 1OE enables/disables outputs 1Y0–1Y3), allowing granular bus segmentation and power-aware output gating in complex multi-peripheral systems.
What package type and ball pitch does the 74LVCH32244AEC/G:5 use?
The 74LVCH32244AEC/G:5 uses the LFBGA96 package (SOT536-1) with 96 solder balls arranged in a fine-pitch grid. Its ball pitch is 0.5 mm, and overall dimensions are 13.5 mm × 5.5 mm × 1.05 mm - optimized for high-density PCB layouts in industrial and automotive control modules.
