54LCX16374 Datasheet | National Semiconductor

Description The LCX16374 contains sixteen non-inverting D flip-flops with TRI-STATE ® outputs and is intended for bus oriented applications. The device is byte controlled. A buffered clock (CP) and Output Enable (OE) are mon to each byte and can be shorted together for full 16-bit operation. The LCX16374 is designed for low voltage (3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX16374 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. Features 5V tolerant inputs and outputs Power down high impedance inputs and outputs Supports live insertion/withdrawal 2.0V- 3.6V VCC supply operation ± 24 m A output drive Implements patented noise/EMI reduction circuitry Functionally patible with the 54 series 16374 ESD performance: Human body model > 2000V Machine model > 200V n Standard Microcircuit Drawing (SMD) 5962-99535 n n n n n n n n Ordering Code Order Number 54LCX16374W-QML Package Number WA48A Package Description 48-Lead Ceramic Flatpack Logic Symbol Connection Diagram Pin Assignment for Cerpack DS101199-1 Pin Descriptions Pin Names OEn CPn I0- I15 O0- O15 Output Enable Input (Active Low) Clock Pulse Input Inputs Outputs Description DS101199-2 TRI-STATE ® is a registered trademark of National Semiconductor Corporation. © 1999 National Semiconductor Corporation DS101199 .national. Functional Description The LCX16374 consists of sixteen edge-triggered flip-flops with individual D-type inputs and TRI-STATE true outputs. The device is byte controlled with each byte functioning identically, but independent of the other. The control pins can be shorted together to obtain full 16-bit operation. Each byte has a buffered clock and buffered Output Enable mon to all flip-flops within that byte. The description which follows applies to each byte. Each flip-flop will store the state of their individual D inputs that meet the setup and hold time requirements on...
