54/74ETL16245 16-Bit Data
Transceiver with Incident Wave Switching
General Description
The 54/74ETL16245 contains sixteen non-inverting bidirec-
tional buffers with TRI-STATE
é
outputs designed with inci-
dent wave switching, live insertion support and enhanced
noise margin for TTL backplane applications.
Both the A and B ports include a bus hold circuit to latch the
output to the value last forced on that pin.
The B port of this device includes 25
X
series output resis-
tors, which minimize undershoot and ringing.
