BDG1A, BDP1A, BDGLA, BPNGA, BPNPA, and
Quad Differential Drivers
Test Conditions
Parametric values specified under the Electrical Char-
acteristics and Timing Characteristics sections for the
data transmission driver devices are measured with the
following output load circuits.
BDG1A, BPNGA, BDGLA, BPPGA (Gates A & B)
12-2271F
BDP1A, BPNPA, BPPGA (Gates C & D)
12-2271.bC

Note: Surges can be applied simultaneously, but never in opposite
polarities.
