The
KK
74HCT157A is identical in pinout to the LS/ALS157. This
device may be used as a level converter for interfacing TTL or NMOS
outputs to High Speed CMOS inputs.
This device routes 2 nibbles (A or B) to a single port (Y) as
determined by the Select input. The data is presented at the outputs in
noninvertered form. A high level on the Output Enable input sets all four
Y outputs to a low level.
TTL/NMOS Compatible Input Levels
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 4.5 to 5.5 V
Low Input Current: 1.0
