It is ideal for low power and very high speed 1.65 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. These 16 bit D-TYPE latches are bite controlled by two latch enable inputs (nLE) and two output enable inputs (OE). While the nLE input is held at a high level, the nQ outputs will follow the data input precisely. When the nLE is taken low, the nQ outputs will be in a normal logic state (high or low logic level) and while high level the outputs will be in a high impedance state. Bus hold on data inputs is provided in order to eliminate the need for external pull-up or pull-down resistor. The device circuits is including 26 Ω series resistance in the outputs. These resistors permit to reduce line noise in high speed applications. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. Flat-48 www.st.com |
