Original Part
Zero Delay Buffer IC 133MHz 1 8-SOIC (0.154", 3.90mm Width)
Alternative Part
1. PI6C2405A-1HWIE Substitution Conclusion
Given identical key electrical parameters (operating frequency, supply voltage, number of channels, and output assignment) as well as package, the PI6C2405A-1HWIE can serve as a direct replacement. However, two critical differences must be noted: its input signal standard is TTL (the original part supports LVTTL), and its outputs are TTL-only (the original part supports CMOS/LVCMOS/TTL). Additionally, while the PLL is present, bypass mode support is not explicitly specified. If the original system relies on LVTTL and CMOS/LVCMOS level interfaces or requires PLL bypass for clock pass-through, level compatibility or timing configuration risks may arise. If the system operates in a pure TTL environment and does not require bypass functionality, direct substitution is acceptable.
2. PI6C2405A-1HWIEX Substitution Conclusion
The substitution conclusion for PI6C2405A-1HWIEX is identical to that of PI6C2405A-1HWIE. Both share the same electrical parameters, with the suffix “X” typically indicating tape-and-reel packaging or an environmentally compliant material version—no electrical performance differences exist. The same limitations apply: narrowed input/output level range (TTL only) and unspecified PLL bypass support. The same conditions govern its use: safe replacement is possible in pure TTL interface applications that do not depend on bypass mode; otherwise, level compatibility and clock architecture adaptation must be evaluated.
