Product speciﬁcation

Quad 2-input NAND gate (open drain)

74LVC38A

AC CHARACTERISTICS

GND = 0 V; tr =tf ≤ 2.5 ns.

Notes

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

2. These typical values are measured at VCC = 3.3 V.

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

by design.
