Product speciﬁcation

Quad 2-input multiplexer

74LVC157A

AC CHARACTERISTICS

GND = 0 V; tr =tf ≤ 2.5 ns.

Notes

1. All typical values are measured at Tamb =25 °C.

2. This typical value is measured at VCC = 3.3 V and Tamb =25 °C.

3. Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed

by design.
