96-ball BGA footprint and board integration
The NXP 74LVC32245AEC,518 is a 32-bit non-inverting transceiver in a 96-LFBGA package (13.5x5.5 mm ball array). The fine-pitch BGA demands a controlled impedance PCB stack-up and a solder paste stencil matched to the 0.5 mm ball pitch — the fan-out vias need to be tented or filled to avoid solder wicking. Four 8-bit elements with independent 3-state output enables bus isolation on separate enable lines — each byte lane can be switched off without affecting the others, useful for multiplexed memory or peripheral buses.
Supply voltage tolerance and signal compatibility
Rated for 1.65 V to 3.6 V supply, the part bridges 1.8 V and 3.3 V logic domains without an external level shifter — the input thresholds track VCC, so a 1.8 V rail drives the inputs cleanly when VCC is 1.8 V, and the 24 mA output drive at both high and low levels meets the VOH/VOL requirements of standard 3.3 V CMOS and LVTTL loads. The 24 mA symmetric output drive (both source and sink) is enough to drive a heavily loaded data bus with multiple fan-outs, but the BGA package's thermal resistance means the total simultaneous switching current should be budgeted per the datasheet's IOL/IOH derating when all 32 bits toggle at once.
Temperature grade and operating environment
Specified for -40°C to +125°C ambient (TA), the part covers automotive under-hood and industrial enclosure environments — the 125°C ceiling allows operation in an engine bay or near a heat sink without derating the supply voltage. The RoHS non-compliant flag means the package uses lead-based solder balls — this part is exempt from RoHS for certain high-reliability applications (e.g., aerospace, medical) but requires a leaded reflow profile and may trigger a waiver for RoHS-compliant BOMs.
Lifecycle and supply posture
No official pin-compatible second source or replacement is listed for this 96-LFBGA variant. If a drop-in alternative is needed, confirm the ball-out and supply voltage range against the original PCB layout — the 74LVC family includes other 32-bit transceivers in different BGA configurations, but the ball map is not guaranteed identical across packages.
