Manufacturer Part Number
74F544MSA
Description
Octal Registered Transceiver
Manufacturer
NSC [National Semiconductor]
Datasheet
C 1995 National Semiconductor Corporation
54F 74F544
Octal Registered Transceiver
General Description
The ’F544 octal transceiver contains two sets of D-type
latches for temporary storage of data flowing in either direc-
tion Separate Latch Enable and Output Enable inputs are
provided for each register to permit independent control of
inputting and outputting in either direction of data flow The
A outputs are guaranteed to sink 24 mA (20 mA Mil) while
the B outputs are rated for 64 mA (48 mA Mil) The ’F544
inverts data in both directions
