Product speciﬁcation

32-bit bus transceiver with direction pin; 30

Ω

series termination resistors; 5 V tolerant; 3-state

74LVC322245A;

74LVCH322245A

RECOMMENDED OPERATING CONDITIONS

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134); voltages are referenced to GND (ground = 0 V).

Notes

1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

2. Above 70

°C the value of P

D derates linearly with 1.8 mW/K.
