Overview

QUAD 2-PORT REGISTER The MC54/74F398 is the logical equivalent of a quad 2-input multiplexer feeding into four edge-triggered flip-flops.
A common Select input determines which of the two 4-bit words is accepted.
The selected data enters the flipflops on the rising edge of the clock.
• Select Inputs from Two Data Sources • Fully Positive Edge-Triggered Operation • Both True and Complement Outputs CONNECTION DIAGRAM (TOP VIEW) VCC Qd Qd I0d I1d I1c I0c Qc Qc CP 20 19 18 17 16 15 14 13 12 11 MC54/74F398 QUAD 2-PORT REGISTER FAST™ SCHOTTKY TTL 20 1 J SUFFIX CERAMIC CASE 732-03 12 S Qa 34 Qa I0a 56 78 9 10 I1a I1b I0b Qb Qb GND LOGIC DIAGRAM I0a S D Qa I1a CP Qa I0b D Qb I1b CP Qb I0c D Qc I1c CP Qc I0d D Qd I1d CP Qd CP NOTES: This diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays.
