具有三态输出的军用 4 通道、4.5V 至 5.5V 双极缓冲器

These bus buffers feature three-state outputs that, when enabled, have the low impedance characteristics of a TTL output with additional drive capability at high logic levels to permit driving heavily loaded bus lines without external pullup resistors. When disabled, both output transistors are turn • Quad Bus Buffers\n• Separate Control for Each Channel\n The SN54125, SN54126, SN74125, SN74126, and SN54LS126A are obsolete and are no longer supplied.;
