74F821–74F863 Series
The 74F821 through 74F863 Series of Octal 9-bit and 10-bit Buffers,
Latch Buffers, Register Buffers and Transceivers are standardized
around the AMD 298XX series with one significant difference—the
Philips Semiconductors “Light-Load” NPN input offers a 50:1
reduction in input loading (1000
μ
A vs. 20
μ
A). This series illustrates
the standardized on 24-pin/300mil-wide Slim-DIP packages,
“broadside” input/output pinouts and control function pins. All
74F8XX 3-State outputs are guaranteed to source/sink
–15mA/64mA, except for the 74F84X Latched Buffers, which are
specified at –15mA/48mA.
The logic diagram and pin configurations of the 74F828
Non-Inverting 10-bit Buffer (Figure 1) and the 74F821–826 and
74F841–846 Registered/Latched Buffers (Figure 4) are excellent
illustrations of the standardized pin configuration illustrating
“broadside” chip design.
Figure 5 shows the pinouts of the 74F827/828 buffers and
74F861–864 Transceivers. There currently are no 9-bit buffer
offerings in this series.
Registered Transceiver Series
the 74F646A–649A and 74F651A–654A Octal Dual-Registered
Transceivers offer a “Light-Load” combination of a 74F245 type
transceiver with two 74F373/374 type octal registers within a 24-pin
Slim-DIP broadside input/output package. This series offers a
significant 6:1 package count reduction advantage over older
technologies.
Figure 6 shows the 74F646A and 74F651A Transceivers Simplified
Block Diagrams, and this series’ pin configurations are depicted in
Figure 7. Figure 8 graphically illustrates four optional storage and
transfer modes of the 74F651A Octal, Non-Inverting, 3-State,
Dual-Registered Transceiver. The 74F654A will be used to explain
the operation of the entire series. The 74F646A/648A (3-State,
INV/NINV) and the 74F647/649 (O.C., INV/NINV) Octal
Dual-Registered Transceivers offer optional signal direction control
This series allows you to store or real-time transfer data in either
direction through the transceiver function. Data at the A
N
port can be
stored in either the A
N
port register or the B
N
register and, then, can
