WITH 3-STATE OUTPUT  
The SN54/74LS373 consists of eight latches with 3-state outputs for bus  
organized system applications. The flip-flops appear transparent to the data  
(data changes asynchronously) when Latch Enable (LE) is HIGH. When LE is  
LOW, the data that meets the setup times is latched. Data appears on the bus  
when the Output Enable (OE) is LOW. When OE is HIGH the bus output is in  
the high impedance state.  
LOW POWER SCHOTTKY  
The SN54/74LS374 is a high-speed, low-power Octal D-type Flip-Flop fea-  
turing separate D-type inputs for each flip-flop and 3-state outputs for bus ori-  
entedapplications. Abuffered Clock (CP) and Output Enable (OE) is common  
to all flip-flops. The SN54/74LS374 is manufactured using advanced Low  
Power Schottky technology and is compatible with all Motorola TTL families.
