1 / 8 page 54FCT373 Octal Transparent Latch with TRI-STATE® Outputs General Description The ’FCT373 consists of eight latches with TRI-STATE out- puts for bus organized system applications. The flip-flops ap- pear transparent to the data 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. Features n TRI-STATE outputs for bus interfacing n TTL input and output level compatible n CMOS power consumption n Output sink capability of 32 mA, source capability of 12 mA n Standard Microcircuit Drawing (SMD) 5962-8764401 Ordering Code Military Package Number Package Description 54FCT373DMQB J20A 20-Lead Ceramic Dual-In-Line 54FCT373FMQB W20A 20-Lead Cerpack 54FCT373LMQB E20A 20-Lead Ceramic Leadless Chip Carrier, Type C Connection Diagrams Pin Names Description D 0–D7 Data Inputs LE Latch Enable Input (Active HIGH) OE Output Enable Input (Active LOW) O 0–O7 TRI-STATE Latch Outputs TRI-STATE® is a registered trademark of National Semiconductor Corporation.
