SN74ALVCH162244 is a 16-bit buffer/driver in the Texas Instruments Widebus family. It uses the Enhanced Performance Implanted CMOS (EPIC) submicron process, and the output ports have equivalent 26-ohm series resistors, so no external resistors are required.
The SN74BCT2423A and SN74BCT2424A are general‑purpose 16‑bit bidirectional transceivers that provide latched multiplexing and demultiplexing of address and data buses. They are suited for microprocessor‑ or bus‑interface applications and memory‑interleaving, offering inverted (2423A) or non‑inverted (2424A) data paths.
The devices feature three 16‑bit I/O ports, active‑low latch enable inputs, and a BCT‑style A/B select line. Detailed pin descriptions, logic symbols, function tables, and a typical memory‑interleave application are included, along with warranty and safety notices.
| Operating Temperature Range | 0°C to 70°C |
|---|---|
| I/O Ports | Three 16‑bit ports (A15‑A0, B15‑B0, AB15‑ABO) |
| Data Path Type | Inverted for BCT2423A, non‑inverted for BCT2424A |
| Package | FN package |
When A/BSEL is low, the A15‑A0 bus is connected to the AB outputs; when high, the B15‑B0 bus is connected to the AB outputs.
ALE, BLE, ABLEA, and ABLEB are active‑low inputs that control data storage; low makes the latch transparent, high latches the data.
