Octal buffer and line driver provides eight non-inverting 3-state outputs for bus interface applications. The device operates over a 2.0 V to 6.0 V supply range and uses CMOS switching levels in the 74HC version. Two output-enable inputs each control four outputs, and a HIGH enable input places the associated outputs in a high-impedance state. Inputs include clamp diodes for current-limited interfacing to voltages above VCC. The family is specified for operation from -40 °C to +125 °C and includes ESD protection exceeding 2000 V HBM and 1000 V CDM.
