SN54BCT374, SN74BCT374 is an 8-bit D flip-flop produced by Texas Instruments. Its feature is that it has 3-state outputs, which can be used to drive high-capacitance or relatively low-impedance loads. It is suitable for implementing buffer registers, I/O ports, bidirectional bus drivers and working registers.
The SN54BCT374 is an octal edge‑triggered D‑type latch featuring three‑state outputs, intended for buffer registers, I/O ports, bidirectional bus drivers, and working registers. It operates from a 4.5 V to 5.5 V supply and offers high‑drive capability for low‑impedance loads.

| Supply voltage (VCC) | 4.5 V – 5.5 V |
|---|---|
| High‑level input voltage (VIH) | 2 V |
| Low‑level input voltage (VIL) | 0.8 V |
| Operating temperature range | -55 °C – 125 °C |
| High‑level output current (I_OH) | 15 mA |
| Low‑level output current (I_OL) | 48 mA – 64 mA |
The device is specified to operate from 4.5 V to 5.5 V.
OE should be tied to VCC through a pull‑up resistor to ensure the high‑impedance state.
