Philips Semiconductors Product specification
Octal D-type registered transceiver; 3-state 74LVC543A
Notes
1. All typical values are measured at T
amb
=25°C.
2. These typical values are measured at V
CC
= 3.3 V.
3. Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed
by design.
