Product Overview
The CD4050B is a Texas Instruments CMOS hex noninverting buffer and converter for Logic use. Its function is six noninverting buffer channels, and it supports one-supply logic-level conversion where the input-signal high level can exceed VCC.
Recommended operation covers a VCC range of 3 to 18 V and an ambient temperature range of -55 to 125 °C. Absolute maximum ratings include -0.5 to 20 V from VCC to VSS, ±10 mA DC input current on any one input, 150 °C junction temperature, and -65 to 150 °C storage temperature.
The device is offered in 16-pin package options including PDIP-16, SOIC-16, SO-16, and TSSOP-16. Pin configuration facts include VCC on pin 1, VSS on pin 8, and no-connect pins 13 and 16. SOIC lead-tip soldering is specified at 265 °C for 10 seconds.
Application fit is grounded in its buffer and converter role: CMOS signal buffering, one-supply logic-level conversion, and DTL or TTL load drive at 5 V under the specified VOL and IOL limits.
