54AC373 54ACT373  
Octal Transparent Latch with TRI-STATE® Outputs  
General Description  
Features  
n ICC and IOZ reduced by 50%  
n Eight latches in a single package  
n TRI-STATE outputs for bus interfacing  
n Outputs source/sink 24 mA  
The ’AC/’ACT373 consists of eight latches with TRI-STATE  
outputs for bus organized system applications. The flip-flops  
appear transparent to the data when Latch Enable (LE) is  
HIGH. When LE is LOW, the data that meets the setup time  
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.  
n ’ACT373 has TTL-compatible inputs  
n Standard Microcircuit Drawing (SMD)  
— ’AC373: 5962-87555
