Description
7434
Buffer & line Driver
6V 2μA IC PDIP-14
The 7434 is a hex buffer IC containing six independent non-inverting buffers in a single package. It is designed to interface TTL-level signals with CMOS circuits, ensuring compatibility and signal integrity in mixed-logic systems. The HC version operates with a supply voltage range of 2V to 6V, making it suitable for 5V systems while retaining the low power consumption and high noise immunity typical of CMOS technology.
This device is characterized for operation over a wide temperature range, meeting both industrial and military specifications. It provides strong output drive capability, capable of driving up to 10 LS-TTL loads, and includes diode protection on all inputs to guard against electrostatic discharge (ESD) and voltage spikes.
Features:
Six independent non-inverting buffer/driver gates.
Improves signal strength and fan-out capability.
Isolates logic stages to protect sensitive circuits.
TTL-compatible logic levels.
Suitable for driving long traces and multiple loads.
