SN54HCT652FK

The SN54HCT652FK is designed as octal bus transceiver which consists of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. Output-enable (OEAB and OEBA) inputs are provided to control the transceiver functions. Select-control (SAB and SBA) inputs are provided to select real-time or stored data transfer. A low input level selects real-time data; a high input level selects stored data.

It has six features. (1) Inputs are TTL-voltage compatible. (2) Independent registers and enables for A and B buses. (3) Multiplexed real-time and stored data. (4) True data paths. (5) High-current 3-state outputs can drive up to 15 LSTTL loads. (6) Package options include plastic small-outline (DW) and ceramic flat (W) packages, ceramic chip carriers (FK), and standard plastic (NT) and ceramic (JT) 300-mil DIPs. That are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1) Its supply voltage range would be from -0.5V to 7V. (2) Its input clamp current would be ±20mA. (3) Its output clamp current would be ±20mA. (4) Its continuous output current would be ±35mA. (5) Its continuous current through VCC or GND would be ±70mA. (6) Its package thermal impedance would be 81°C/W for DW pachage and would be 67°C/W for NT package. (7) Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics about it. (1) Its output voltage high would be min 4.4V and typ 4.499V at Vcc=4.5V and Ioh=-20uA and it would be min 3.98V and typ 4.3V at Vcc=4.5V and Ioh=-6mA. (2) Its output voltage low would be typ 0.001V and max 0.1V at Vcc=4.5V and Iol=20uA and typ 0.17V and max 0.26V at Vcc=4.5V and Iol=6mA. And so on.
