DP8310,DP8311 DP8310/DP8311 Octal Latched Peripheral Drivers Literature Number: SNOSBE4 DP8310/DP8311 Octal Latched Peripheral Drivers General Description The DP8310 and DP8311 Octal Latched Peripheral Drivers provide the function of latching eight bits of data with open collector outputs, each driving up to 100 mA DC with an operating voltage range of 30V. Both devices are designed for low input currents, high input/output voltages, and feature a power up clear (outputs off) function. The DP8310 is positive edge latching. Two active low write/ enable inputs are available for convenient data bussing without external gating. The DP8311 is positive edge latching. The active low strobe input latches data or allows fall through operation when held at logic "0". The latches are cleared (outputs off) with a logic "0" on the clear pin. Features n High current, high voltage open collector outputs n Low current, high voltage inputs n All outputs simultaneously sink rated current "DC" with no thermal derating at maximum rated temperature n Parallel latching or buffering n Separate active low enables for easy data bussing n Internal "glitch free" power up clear n 10% VCC tolerance Applications n n n n n n n n n High current high voltage drivers Relay drivers Lamp drivers LED drivers TRIAC drivers Solenoid drivers Stepper motor drivers Level translators Fiber-optic LED drivers Connection Diagrams Dual-In-Line Package Dual-In-Line Package DS005246-1 Top View DS005246-2 Top View Order Number DP8310N or DP8311N See NS Package Number N20A (c) 2000 National Semiconductor Corporation DS005246 www.national.com DP8310/DP8311 Octal Latched Peripheral Drivers February 2000 DP8310/DP8311 Absolute Maximum Ratings (Note 1) Note: *Derate N20A package 15.4 mW/C above TA = 25C, JA = 65C/W.
