MM54HCT643/MM74HCT643  
True-Inverting Octal TRI-STATE Transceiver  
General Description  
TheseTRI-STATEbi-directionaltransceiversutilizeadvanced  
silicon-gate CMOS technology and are intended for two-way  
asynchronous communication between data buses. They  
have high drive current outputs which enable high speed  
operation even when driving large bus capacitances. These  
circuits possess the low power consumption of CMOS cir-  
cuitry, yet have speeds comparable to low power Schottky  
TTL circuits.  
MM74HCT640 transfers inverted data from one bus to the  
other. The MM54HCT643/MM74HCT643 transfers inverted  
data from the A bus to the B bus and non-inverted data from  
the B bus to the A bus.  
MM54HCT/MM74HCT devices are intended to interface be-  
tween TTL and NMOS components and standard CMOS  
devices. These parts are also plug-in replacements for LS-  
TTL devices and can be used to reduce power consumption  
in existing designs.  
All devices are TTL input compatible and can drive up to 15  
LS-TTL loads, and all inputs are protected from damage due

Both the MM54HCT640/MM74HCT640 and the  
MM54HCT643/ MM74HCT643 have one active low enable  
input (G), and a direction control (DIR). When the DIR input  
is high, data flows from the A inputs to the B outputs. When  
DIR is low, data flows from B to A. The MM54HCT640/
